2, Loose, beacuse it's easier to loose on electron than to gain seven electrons.
3, Gain, beacuse it's easier to gain one electron than to loose seven electrons.
4, They are the same amount.
5, There are more protons than electrons.
Conclusion: The number of electrons in the valence shell (outer shell) determines whether the atom will gain or loose electrons. If the number is closer to eight, then it will gain electrons; If the number is closer to zero, then it will loose electrons. Also, if the number of protons exceed the number o electrons, the atom will be positive; Whereas if the number of electrons exceed protons, the atom will be negative.
