## Homework Statement

Predict how many electrons will most likely be gained or lost by each element:

In this case, Gallium

## Homework Equations

None (that I know of)

## The Attempt at a Solution

[/B]

I know that Gallium is a metal, and metals tend to lose electrons to become cations, so I will assume that Ga will be losing electrons. At the top of the column in which Ga resides sits the term 3A, which I understand to be the number of valence electrons each element in the column has. Beyond this, I have no idea what I am doing. Can someone explain how to predict how many electrons a given element will gain or lose? Thank you in advance.
