Nitrogen has a total of five valence electrons in its ground state.

Nitrogen is a nonmetal and a gas that belongs to the periodic table's p-block elements. It is located in the second period and 15th group of the periodic table.

It has a mass number of 14 and an atomic number of 7. It has the following electrical configuration: 1s²2s²2p³.

Now, according to the following statement: The atomic number of an element is always equal to the number of electrons present in that element's atom. And the electrons in an atom's outermost valence shell are known as valence electrons.

Hence, the electronic configuration of the nitrogen atom reveals that the number of electrons present in the outermost shell, i.e., the second shell, is 5 electrons.

Thus, nitrogen has a total of five valence electrons in its ground state.
