How is an atom and ion different?
An atom has a charge and an ion has no charge.
An atom has no charge and an ion has a charge.

+1
-1
-2
What charge will elements in group 13 have (once they lose 3 electrons)?

All atoms can become stable by...
losing or gaining electrons to obtain a full valence (outer) shell
losing or gaining protons to obtain a full valence (outer) shell
losing or gaining neutrons to obtain a full valence (outer) shell
If an atom has 7 valence electrons, what will its charge be as an ion once it gains stability?
+1
+7
