Answer :

Final answer:

Nitrogen is a nonmetal, as it's located in Group 15 at the top of the periodic table and forms an anion called a nitride ion (N³⁻). In a reaction with aluminum, aluminum would form an Al³⁻ cation, while carbon would form a C⁴⁻ anion.Thus Option 2 is correct.

Explanation:

Nitrogen is found at the top of Group 15 on the periodic table and exhibits properties typical of a nonmetal. This classification means that it lacks the characteristics of metals, tending to be a poor conductor of electricity and heat, and in its elemental form, it is a gas at room temperature. Nitrogen atoms have the ability to gain three electrons to achieve a stable electron configuration similar to the noble gas neon, forming an anion known as the nitride ion (N³⁻).

When discussing reactions involving the formation of ions, such as the reaction between aluminum and carbon to create an ionic compound, aluminum (being a metal) will lose electrons to form a cation with a charge of 3+ (Al³⁻), while carbon will gain electrons to form an anion with a charge of 4- (C⁴⁻).
