What ion does oxygen form when it gains 2 electrons. Originally Oxygen had 8 electrons and 8 protons. Protons - electrons = charge.

• O^-6, it now has 8 more electrons than protons

• O^-2, It now has 2 more electrons than protons

• O⁺², it now has 2 more protons than electrons.

What ion does Magnesium form? Protons - electrons = charge.

• Mg^-2​, gains 2 electrons, it has 2 more electrons than protons.

• Mg⁺², loses 2 electrons, it has 2 more protons than electrons.

• Mg^-6, gains 6 electrons, it has 6 more electrons than protons

What ion would F form?

• F^-1, Because it will gain one electron making it have 1 more electron than proton.

• F⁺⁷, because it will lose 7 electrons making it have 7 more protons than electrons.

According to the diagram below, how many bonds will this atom be able to make?

• 1

• 2

• 3

• 4
