To do today's assignment, start by creating a model of the "Electron Shells in an Atom" that looks just like the picture below. It illustrates the fact that each orbital of electrons around the nucleus of an atom holds a specific number of electrons.

 

 

Each shell can have less than the maximum that shell can hold but no more. Once one shell is filled, the remaining electrons go into the second shell. If that shell is filled then the remaining electrons go onto the nest shell and so on.

Next, we reviewed the content covered in my YouTube video from Wednesday by completing the first section on the next worksheet.

We began by reviewing what each of the 4 parts of a block on the Periodic Table means. Then we listed the stats that the block shows about how many protons, electrons, and neutrons are in an atom. If you still don't understand then go back and watch the YouTube video from Wednesday.

 

We then drew a model of a Beryllium atom with the correct number of protons, neutrons, and the correct number of electrons in each shell.

 

For the remaining 5 items on the worksheets you will do the same thing as for beryllium.

 

 

Choose an element from periods 3, 4, and 5 and do the same thing for each of them as we did for beryllium in the sample at the top of the worksheet.

We finished the Zoom session by watching a video that further explains about the Periodic Table and what it means. If you missed the Zoom session, please watch it.
