71%

An ion represented as AXy−^{A}\text{X}^{y-}AXy− has a mass number (AAA) of 34.

The number of electrons in this ion is 12.5% greater than the number of its protons, and the number of neutrons is equal to the number of electrons.

Which of the following correctly identifies the species AXy−^{A}\text{X}^{y-}AXy−?

A

34S2−^{34}\text{S}^{2-}34S2−

B

34S2+^{34}\text{S}^{2+}34S2+

C

34Cl−^{34}\text{Cl}^{-}34Cl−

D

34P3−^{34}\text{P}^{3-}34P3−
