Final answer:
Nitrogen forms an anion with a 3- charge as it gains three electrons to have the same number of electrons as neon, becoming a nitride ion with the symbol N³-.
Explanation:
When forming an ion, nitrogen will typically achieve a charge of 3-. This occurs because a nitrogen atom, which resides in group 15 of the periodic table, gains three electrons to complete its valence shell, obtaining a configuration similar to the nearest noble gas, neon, making nitrogen an anion. This results in a nitride ion, with the symbol N³-.
Let's consider an example with aluminum and carbon forming an ionic compound. Aluminum, from group 13, will lose three electrons to form an Al³+ cation, whereas carbon, needing four additional electrons to complete its octet, is unlikely to form a simple carbid ion in most conditions. Instead, aluminum may react with nitrogen, not carbon, to form AlN, where nitrogen will be the N³- anion.
Answer:
The valence electrons of nitrogen in its compounds are all sp³ hybridized orbitals. The formal charge on N is usually -1 for an anion, 0 for a neutral compound, and +1 in cations. A nitrogen atom with a formal charge of -3 would correspond to a nitride ion, N³⁻, which is strongly basic in aqueous solution. Hope this helps...
