nonmetal elements...how do u figure it out?
2006-12-10 07:23:58 · update #1
This group (we call it Group 3 in the UK) consists of metals and non-metals. At the top of the group is the non-metal boron, which does not form positive ions. When it bonds covalently, there is a problem, and that is that it usually only has 6 electrons in its outer level.
The other metals in the group have a normal 3+ charge, except thallium (of recent world-wide fame) which tends to be +1. This is called the Inert Pair Effect.

they generally form a +3 ion

They generally have 3 more electrons than the nearest noble gas so they would tend to lose those 3 electrons and become +3

1A = +a million ions they have one extra electron than they choose for finished valence shells. 2A = +2 ions they have 2 extra electrons than they choose for finished valance shells. 7A = -a million ions they desire a million extra electron to have finished (and stable) valence shells.
