Answer :
The statement "the doubly charged ion N₂²⁺ is formed by removing two electrons from a nitrogen atom." is true.
When two electrons are removed from a nitrogen atom, it becomes a doubly charged ion, N₂²⁺. This process is called ionization. Nitrogen has 7 electrons in its neutral state. When it loses two electrons, it has 5 protons and 5 electrons, making it a positive ion with a charge of +2.
Ionization usually occurs when an atom absorbs enough energy, such as from heat or light, to cause the electrons to break free from the atom's nucleus. The N₂²⁺ ion is relatively uncommon, but can be observed in certain high-energy environments or during specific chemical reactions.
