السؤال 117

A monatomic ion has a two-plus charge. Which particle-count relationship must it have?

Equal numbers of protons and electrons
Two fewer protons than electrons
Two fewer electrons than protonsالإجابة الصحيحة
Two fewer neutrons than protons

الشرح

A two-plus charge means positive charge exceeds negative charge by two units, so the ion has two fewer electrons than protons. Giving it two extra electrons would instead produce a two-minus charge.
