Use Lewis symbols to represent the electron transfer between the following atoms to give ions with noble gas configuations:
A. Mg and S
B. Ba and I
I can't draw these on the computer or these boards.
Mg: is the neutral Mg atom.
:S: is the neutral S atom.
Now move the two electrons on Mg to the bottom of S. That leaves Mg with no electrons and a 2+ charge and it leaves S with 8 electrons and a 2- charge.
Ba and I are done the same way except the formula is BaI2 so 1 electron from Ba is transferred to one of the I atoms and the other electron from Ba is transferred to the other I atom. Ba then carries a 2+ charge and each I carries a -1 charge.
