What is an ion?
An atom or group of atoms that has lost or gained electrons to form a charge
What piece of information does the group number of an element tell you?
The number of (outer shell) electrons in an atom of that element
At what electron configuration are atoms most stable?
With a full shell of electrons
Which group of elements is completely unreactive because they already have a full outer shell?
The Noble Gases (Group 0)
