Questions: What is the ion symbol for the phosphide ion? P^3-

Solution Steps

Phosphorus typically forms an ion by gaining three electrons to achieve a stable electron configuration similar to the noble gas argon. This results in a charge of \(3-\).

We need to find the ion symbol that correctly represents phosphorus with a \(3-\) charge.

• \(p^{2-}\)
• \(\mathrm{P}^{3-}\)
• \(\mathrm{P}_{2}{ }^{2-}\)
• \(P^{3-}\)
• \(P^{5-}\)

The correct ion symbol for the phosphide ion is \(\mathrm{P}^{3-}\).
