EXAMPLE:

Sodium 1s22s22p63s1 = [Ne]3s1

Lithium 1s22s1 = [He]2s1

This pattern is seen in columns 1-2 and 13-18 of the PT

What other patterns might exist within the PT?

Maybe there is a reason why the PT has that weird shape!

2. Electron Configuration

Because of electron shielding, electrons in the inner orbitals are closer to the nucleus and more tightly bound to it. So they are rarely involved in chemical reactions.

This means that the chemistry of an atom depends mostly on the

electrons in its outermost orbital,
