Question

What is the pattern in the charge for elements in each group on the periodic table?

Answer 1

( besides the transition metals) the group shows charge with...
1, +1 charge ( loses to group 17)
2, +2 charge
13, +3 charge
14, ±4 charge ( depends on if this is a metal or nonmetal( metalloids are classified by which side of the staircase))
15, -3 charge
16, -2 charge
17, -1 charge ( gains from group one ( halogens(17) and alkali metals (1) are highly reactive).
18, no charge (noble gasses are always full with valence electrons, thus have no charge and rarely form compounds.)
