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 .

answer; ///electron cloud
