2. The Father of the Periodic Table Dimitri Mendeleev
_______________was the first scientist to notice the relationship between the __________
Arranged his periodic table by ________ _______

6. 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 atomic orbitals.
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.

7. Groups = Columns (called Families)
The elements in a group have the same number of electrons in their outer orbital.
Every element in the first column (group one) has one electron in its outer shell. Every element on the second column (group two) has two electrons in the outer shell. As you keep counting the columns, you'll know how many electrons are in the outer shell.
There are some exceptions to the order when you look at the transition elements, but you get the general idea.
