The statement which is true about the reactivity of element with 1S²2S²2P⁶3S¹ is

it is reactive because it has to lose one electron to have a full outermost energy level.

Explanation

Element with 1S²2S²2P⁶3S¹ electron configuration is a sodium metal. sodium has one electron in the outermost energy level. for sodium to have a full outermost energy level (8 electrons) it loses the 1 electron in 3S¹ to form a positively charged ion. (Na⁺)
