Something was learned. The hypothesis then can be altered and the experiment tried again. Read through the pages. Pay attention to the last few pages, which introduce several new concepts. Remember that a compound includes the number of atoms of each element in that compound. For example, CO contains one carbon atom and one oxygen atom. A chemical reaction is displayed similar to a mathematical problem with each side having the same mass. Remember that matter cannot be created nor destroyed in a reaction; therefore, the number of atoms must also be equal in number, but not necessarily in arrangement.
Reactions will be covered more in depth at a later date. Try the test. Try the quiz. Try to recite them and explain them to your parents. Use your periodic table if needed. Lesson 30 Try the isotope problems. To calculate an average, you would multiply each mass times the decimal form of the percent for each isotope. Then, add together those values.
This is also shown in the answer. Complete question 3 using the periodic table. Write a physical and chemical property of a piece of paper. Answer: example-made from wood, burns What identifies an atom? Answer: protons and neutrons An atom is equal when it has the same number of protons as what? Answer: electrons Record your score out of 7 for the problems and questions. Read more about isotopes: one , two. Again, it introduces a new concept, radioactive decay. Just be aware that some isotopes are unstable and give off protons, making a totally new element with another element or particle released.
Remember that when the atomic number changes, it becomes an entirely new element. Look at the examples that show this. Watch the video on electrons in the atom. Who was Neils Bohr? Max Planck? What is the equation used for the wave description of light? Check your notes to see if you were right. Learn a little bit about wavelength and frequency problems. Can you find the wavelength of a radio wave with a frequency of 90 MHz? Answer: 3. It is an experiment and the screen is black for a bit. Watch the first four minutes and twenty-seconds. Watch the video on electron distribution and take notes and fill in what you can of the chart.
Copy the diagonal rule when prompted. Lesson 34 Answer the questions that follow. You will follow the directions and use this site on electron distribution. Choose s orbitals and state its shape. Choose p orbitals and state the shape of the px orbit. Choose d orbitals and state how many lobes a typical d orbital has. Choose f orbitals and state how many orbitals are in the f sublevel.
For Quiz 3 and 4, count the number of electrons as before, then look the final number up as the atomic number on the periodic table where you will find the chemical symbol or name. How did you do? Practice more with these quizzes if you are having trouble. Use your electron configuration chart from yesterday to try Quiz 5 at the same site above. Remember to put a number and letter in the first box and the number of electrons of that orbital in the raised box. Study your electron configuration chart from yesterday.
Can you duplicate it? The orbitals are labeled s, p, d, f. Sometimes it is useful to make up an acronym to memorize this order. It contains those letters which I capitalized in the correct order. Use your periodic table to assist in finding the atomic number and element. Hint: Each half-arrow represents one electron. Note that electrons fill the orbital spaces one at a time, then fill in the second electron to make a pair as the number of electrons increases.
Record your score out of 14 for the orbital diagram. Each time it starts you over, you lose one point. You will need at least dried beans or peas. Lesson 36 Complete the lab. You could use the graphing application you saved from the first unit or create your own graph. Complete the lab report using the lab report directions. Score your lab out of 20 points.

Use your periodic table as needed. You may use your periodic table and electron configuration chart if needed. Score 2 points per answer some questions have more than one answer. There are 39 answers all together for a total possible of Record your score out of a total of 74 points.
Add any extra credit to your score, not the total, 2 points per answer. When the class on the video pauses to do their element organization, you do the same. Take the first 15 elements and try to organize based on the final term of the electron distribution valence electrons. Organize with increasing atomic number. Pay attention in the video on how to use the periodic table when figuring out electron distribution. This will help you tremendously. Pause the video when prompted and really try to complete the exercises.
Remember what he says about the d-block having the first number as one less than you would think from the periodic table. If the d-block is in the 5 th row, you would start that block with the number 4. For example, Iron Fe with atomic number of 26 in the fourth row, would use 3d rather than a 4. You would use one less than 4, which would be 3. This section takes a lot of practice. Here are the answers for the video quiz. Who did what? Match the accomplishments to either Mendeleev or Moseley. Continue on page 4. Try the Noble Gas Distribution below the matching. Do the questions in the boxes for a grade. Note the chemical symbol corresponds to its Latin name.
Try to familiarize yourself with these oddball symbols. It will help when you come across them in the future. There is no additional work to submit for a grade. You also need colored pencils or something like them. Watch the video on the organization of the periodic table. There is additional information on the elements in the table besides the electron distribution. Here are the answers to the video quiz. But maybe it will inspire you to learn it too. Use your periodic table. You add up the digits for the highest level number in this case, 2. Remember that an energy level is all of the electrons in that level number. For example an element with electrons in the 1s, 2s, and 2p use 2 energy levels not 3.
An element with electrons in 1s, 2s, 2p, 3s, and 3p, uses 3 energy levels not 5. Lesson 43 Another elements song! Take a listen and learn about their uses. Use your notes and the periodic table if needed. What is the noble gas distribution for phosphorus? Record your score out of 9 for those, plus the noble gas questions above. Do this element quiz. Pay attention to the trends and the scientific explanations as to WHY the trends exist. Some are more obvious than others and based on information you already know. Ionic charges: Remember the noble gases on the right of the periodic table are stable, that is, their valence energy levels are full.
To accomplish this, the atoms will lose or gain electrons to try to achieve that state of the noble gas with the outer-most level full. In the video, he hints that losing electrons is like giving to others, which is a positive thing. So, when an atom loses electrons, it has a positive charge. Also, think about it. If you lose negatively-charged electrons, you now have more positive protons in the nucleus, giving the atom an overall positive charge.
Does that make sense? If you add negatively-charged electrons, you end up with more electrons than protons, giving the atom a more negative charge. Here are the video quiz answers. Record up to 20 points for completing the chart. Do you understand WHY the trends are what they are? You must know the definitions of the property to be able to understand why. Complete the questions for a quiz grade. Try the ScienceGeek review quiz. They are opportunities to learn. Take advantage of them! Study what you have learned so far. This is the end of the first quarter.
Calculate your quarterly grade. Your goal is to get an A. Remember a stable ground state is when an element has a full valence level. An ion would be when it was missing an electron. You can make elements stable and unstable here. PDF version Print off the graphs and put them in your lab notebook. Answer the questions in complete sentences, making sure to restate the question in each answer. Your answers should make clear what the question was.
Grade your lab based on the provided rubric. Divide your score in half. Revisit pages if you need extra practice. Be sure you can do electron configurations, valence levels, noble gas distribution, and figure out stable ions. Remember the Cl ion question in the card matching is incorrect. Know about Mendeleev and Moseley. Your test is on Lesson Here are my answers to the first one. If you think I messed up, write and tell me and explain. These are all listed on the materials list at the top of the course. How is it that every substance in the universe is made from different combinations of only known elements?
Through bonding! Elements combine to form ionic compounds, covalent compounds, also known as molecules, and metals. You will need this for today and future use. Complete the lab. Read through all the directions before you start. Begin the lab report. Score your lab based on the rubric, points , and then divide your score in half. Follow along in your notes and take additional notes as needed. Pause the video and do the practice problems. Check your answers with the video. For example, Aluminum will have one dot on three sides, not two dots on one side and one on another. Nitrogen will have a dot on each of the four sides, then add an additional dot for each side until you get 5 total or the specific number of valence electrons on the periodic table.
Lewis structures are different. Keep practicing. Record 10 points for completing the assignments. Check your answers in the matching below. Watch the review video. This teacher tells his students to complete the dot diagram by filling in two dots electrons on one side representing the s2 orbital then fill in one on each of the other sides before coming back and filling in the second dot electron on those three other sides representing the p6 orbital. That is another and probably more correct way to complete the dot diagram. So it will also not be done on the test.
Just be aware of this difference. You can skip the history lesson around the ten minute mark. You watched the beginning of this already. You can watch it again if you want the review, or you can skip to Lesson 54 Practice Lewis Structures from Lesson 52 for extra practice. Complete the activities on the page. Record 20 points for completing the assignments without cheating and with correcting and understanding your mistakes. Be familiar with the types of bonds and the relationship with electronegativity.
