The electronic configuration of an element is given below. 1s22s22p63s1 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 reactive because it has to lose one electron to have a full outermost energy level. it is unreactive because it has to gain one electron to have a full outermost energy level.

Option (c) is the correct answer.

Explanation:

Reactivity is defined as the ability of an atom to react with another atom in order to attain stability.

For example, an element with electronic configuration shows that there is only one valence electron present in the outermost shell.

Therefore, to attain stability this atom will readily react in order to lose one valence electron.

Thus, we can conclude that the statement it is reactive because it has to lose one electron to have a full outermost energy level, is true about the reactivity of the given element.
