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.

you didnt put any of the following

water and alcohols have similar properties because water molecules contain hydroxyl groups that can form hydrogen bonds with other water molecules and with alcohol molecules, and likewise alcohol molecules can form hydrogen bonds with other alcohol molecules as well as with water.
