Na has a lower ie1 than mg, but mg has a lower ie2 than na because: the radius of na is smaller than that of mg. ie1 increases from left to right across a period and ie2 decreases from left to right across a period. the radius of mg is larger than that of na. ie1 decreases from left to right across a period and ie2 increases from left to right across a period. ie1 increases from left to right across a period. however, because na has only one valence electron, ie2 for na involves the removal of a core electron − requiring significantly more energy.

answer

fusion: the energy source of stars. the energy released from the collapse of the gas into a protostar causes the center of the protostar to become extremely hot. when the core is hot enough, nuclear fusion commences. fusion is the process where two hydrogen atoms combine to form a helium atom, releasing energy.
