How many valence electrons are in the neutral atom of phosphorus (provide only a numerical answer i. e. 1, 2, 3, etc.)

5

Explanation:

Valence electrons refers to the number of electrons in the outermost orbital of an atom that determines it's ability to bond with others.

Majority of the time, the valence of an atom is the same as the group number in which he element belongs to.

The electrons per shell is; 2, 8, 5

Phosphorus with the symbol P, belongs to group 5.

5 is the answer.

there are no statements provided but here is why:

sulfur belongs to group 16 because it can be found in nature whether it is in a free or combined state.

"hydrogen bonding is the attraction of h atoms in the water molecule (slight + charge) to o atoms in a neighboring water molecule (slight - charge); it is a weak interatomic force. but it is still strong enough to the water molecules "stick" together."
