The valence electron of the atom is 5

Valence electron(s) are electrons located on the outermost shell of an atom.

From a detailed understanding of arrangements of electrons around the nucleus of an atom, we discovered that the 1st shell can hold a maximum of 2 electrons while other shells a maximum of 8 electrons.

From the question given above, the atomic number of the atom is 7. Thus, we can obtain the valence electron as follow:

Atomic number = 7

1st shell = 2

2nd shell = 5

The 2nd shell is the last shell of the atom. This shell contains 5 electrons. Therefore, the valence electron of the atom is 5.
