Gaining electrons lead to decrease in oxidation state.
A nitrogen atom needs to gain three electrons to achieve a stable electron configuration similar to a noble gas. This would result in the nitrogen atom having a full outer electron shell, like that of a noble gas.
nitrogen
It gains three, loses five, or shares pairs of electrons
To achieve a noble gas configuration, nitrogen needs to gain three electrons to have a completely filled outer shell like neon. This would give it a charge of -3 since each gained electron carries a negative charge.
Three. In fact, any element in the same column of the periodic table as nitrogen will also gain three electrons when forming an ion.
Nitrogen must gain three electrons.

The charge of nitrogen can be determined by looking at the number of electrons it has gained or lost in order to achieve a stable electron configuration. In its most common form, nitrogen has a charge of -3, as it typically gains three electrons to complete its outer shell of electrons.
Nitrogen has to gain three electrons
Nitrogen gas does not gain or remove electrons. Therefor this gas is neutral.
Nitrogen will gain three electrons to form a nitride anion with a charge of -3.
Nitrogen's atomic number indicates that it contains 7 electrons. Two of them are in the inner, non valence shell, leaving five in the valence shell, which can contain a maximum of 8. Therefore, to form a stable ion with a noble gas electron configuration, nitrogen must gain 3 electrons. Such ions are actually found in some metallic nitrides. To form a cation with a noble gas configuration, nitrogen would have to lose 5 electrons. In practice, nitrogen does not form simple cations. However, note that nitrogen participates in many different kinds of covalent bond, in which electrons are shared with other atoms, rather than being lost to other atoms or gained from them.
nitrogen has 5 valence electrons. It should gain 3 electrons to achieve a noble gas configuration.
Nitrogen has an oxidation number of -3. Since it is in group 15, it has 5 valence electrons. It wants to have eight, so it will gain three electrons. Electrons are negative, that's why the oxidation number is negative.
Chlorine typically gains one electron to achieve a stable electron configuration, forming a chloride ion with a -1 charge.
Nitrogen can gain 3 electrons to achieve a full outer shell with 8 electrons, or lose 5 electrons to achieve a stable electron configuration similar to the noble gas neon.
5 valence electrons because it needs to gain 3 electrons in order to become stable
