•Each column iscalled a “group”

•Each element in agroup has the samenumber of electronsin their outer orbital,also known as“shells”.

Except for He, ithas 2 electrons

•The electrons in theouter shell are called“valence electrons”

• Helium is the exception in Group 8.

• Since it has just one shell, that shellcan only fit 2 electrons instead of 8.

• It is in this group because all theelements have a full outer shell.
