Asodium atom has 1 valence electron in its third shell. what will it do when forming an ion? a. gain 1 valence electron b. lose 1 valence electron c. gain 7 valence electrons d. lose 7 valence electrons

When forming an ion, this sodium atom will lose 1 electron, as it is the easiest way to form a full shell, as opposed to gaining 7 electrons.

a boiling water reactor does not boil the water. a pressurized water reactor boils the water faster. a pressurized water reactor is heated directly by the core. a pressurized water reactor does not use fission.
