Bonding Review

Bond formed by the transferring of electrons. Occurs between a metal (loses electrons) and a nonmetal (gains electrons).

• Ionic bond

• Ion

• Product

• Molecule

Numerical charge of an ion that indicates the number of electrons lost, gained, or shared. For example, a +1 means an atom lost 1 electron whereas a 3 means an atom gained 3 electrons.

When an atom loses an electron, it becomes a

• positive ion

• negative ion

• neutral ion

• neutral atom

Why do all bonds form?

• so the number of protons equals the number of electrons

• so an atom can become unstable

• to fill the outermost energy level
