The electronic configuration of an element is given below. 1s22s22p5 Which statement about the reactivity of the element is true? It is reactive because it has a full outermost energy level. It is unreactive because it has a full outermost energy level. It is unreactive because it has to lose one electron to have a full outermost energy level. It is reactive because it has to gain one electron to have a full outermost energy level.

The statement that is true about the reactivity of element with 1S² 2sS²2P⁵ electronic configuration is

It is reactive because it has to gain one electron to have a full outermost energy level

Explanation.

The element's reactivity is tendency of an element to gain or to loss electrons.

Metals react by losing electrons while non metals react by gaining electrons.

since P orbital can hold a maximum of 6 electrons, Element with 1S²2S²2P⁵ electronic configuration gain 1 electron to fill 2P⁵ energy level.
