Nitrogen gas (N2) is a diatomic molecule, meaning it consists of two nitrogen atoms bonded together. In its natural state, nitrogen gas is electrically neutral. This means it has no net charge.
Each nitrogen atom has an atomic number of 7, which means it has 7 protons in its nucleus and 7 electrons surrounding the nucleus. In a nitrogen molecule (N2), the two nitrogen atoms share three pairs of electrons, forming a triple bond. This sharing of electrons ensures that the molecule remains neutral.
Therefore, the charge of nitrogen gas is 0.
