Objective
Tonight’s Homework
To learn about element
symbols and names
Research any element from 37
or higher. Create a small poster
by Friday
Building a Periodic Table
Friday you’re going to come in with two small posters
about 2 elements of the periodic table. Your tiny posters
need to be squares 3 inches on a side.
You need to pick one element lower than #50 and one
element above #50.
They need to show the following:
ELEMENT NAME

Notes on Atomic Symbols
If we look at an element in chemistry, there are
a few things we want to be aware of.
4-
3 Cl 2
The “3” in front represents 3 molecules. 3
separate groups of Chlorine.
The “4-” in the corner means that each group
has 4 extra electrons.
The 2 in the lower right means that our chlorine
comes in pairs. 2 atoms for each molecule.
Filling in your periodic table
You’ll notice that the table you were given last week is
mostly blank. Your job for the rest of class (and for
homework if you don’t finish) is to finish filling in the
different elements and color coding different regions.
Using page 144 of your book, you need to:
1) Fill in all the elements the way hydrogen has been
done
2) Color-code regions the same way they have on page
144. (a key is in the lower left of the page)
3) Get the heavy stairstep line on the right-hand area
4) For elements 104 to 114, look at the table on the wall
