Answer: Option (C) is the correct answer.
Explanation:
As nitrogen is a group 15 element so, it means that common electronic distribution of elements of group 15 will be 2, 8, 5.
Hence, it means that all the elements of group 15 have 5 valence electrons.
Valence electrons are the electrons that are present in the outermost orbital shell.
Whereas atomic number of nitrogen atom is 7 and its atomic mass is 14. Therefore, it contains 7 protons and 7 neutrons in its nucleus.
Thus, we can conclude that nitrogen is a group 15 element it implies that nitrogen has 5 valence electrons.
