Predict the charge on this nonmetal anion

• +1

• -1

• +7

• -2

How many valence electrons?

• 1

• 2

• 8

• 20

What is the first thing to decide about an element before you can predict the charge?

• What is its atomic number

• What period (row) is it in

• Is it a metal or a nonmetal

• Who discovered it

Once we know the number of valence electrons, how do we predict the charge on a metal ion?

• The charge will be + the number of valence electrons

• The charge will be - the number of valence electrons

• Subtract the number of valence electrons from 8 and make it +

• Subtract the number of valence electrons from 8 and make it -
