TODAY’S OBJECTIVE Today you will distinguish between the groups on the periodic table. HS-PS1-1: Use of Periodic Table to predict relative properties of elements based on locations in the Periodic Table.

You've got Your Periods... Even though they skip some squares in between, all of the rows go left to right. When you look at a periodic table, each of the rows is considered to be a different period (Get it? Like PERIODic table.) quoted from

Periods = Rows In the periodic table, elements have something in common if they are in the same row. All of the elements in a period have the same number of electron shells. Every element in the top row (the first period) has one orbital for its electrons. All of the elements in the second row (the second period) have two orbitals for their electrons. It goes down the periodic table like that.electrons Periods also tell us the energy level of an atom. quoted from

Period Shell Activity Draw the number of shells each element should have per period on the periodic table sheet provided to you.

Families on the Periodic Table Columns are also grouped into families. Families may be one column, or several columns put together. Families have names rather than numbers. (Just like your family has a common last name.)

Color Coding the Periodic Table Will be passed out and I’ll introduce it. Read the Introduction to Color Coding the Periodic and Highlight Underline any special parts you think you will need to know for tomorrow.
