When elements gain or lose electrons to form ions,
1. their nuclei become more stable
2. they have the electron configuration of a noble gas
3. they become noble gases
4. they become unstable
When forming ions, metals can be expected to _________ electrons while nonmetals can be expected to __________ gain electrons.

Ionic compounds are ordinarily found as
1. liquids
2. gases
3. plasma
4. crystals
Ionic compounds are held together by
1. electrostatic forces - opposites attract.
2. nuclear forces that overcome the repulsion of similar charges.
3. gravitational forces, since the ions are not the same size.
4. unknown forces - no one is certain what holds ionic compounds together.

Pretend that a new alkaline earth metal, with an atomic number of 120 is produced. It would initially be given the symbol Ubn (Un-Bi-Nilium, or 1-2-0-ium). If you could react this new atom with the already synthesized halogen, Uus (Ununseptium, 117), what would be the formula of the ionic compound that they would form? (By the way, 117 is too unstable and would decay in a less than a millisecond. The same would likely be true of 120, so you could never actually test this out!)

2. Ubn₂Uus₃
3. Ubn₂Uus
4. UbnUus
