Question

When a sodium (Na) atom forms an ion so that it looks like a noble gas with a full valence shell, what will its charge be?
2-
1-
3-
2+
1+
3+

Answer 1

Answer:

I believe 1+

Explanation:

when Na loses 1 electron in the outer shell it has 8 valence protons on it's new most outer shell. so now it has 11 protons and 10 electrons. that extra proton (positively charged) adds one extra charge. so +1
