Question 1

Which equation correctly shows the formation of a Group 2 metal ion?

X\text{X}X represents a Group 2 metal and e−\text{e}^-e− represents an electron.

A

X+2e−→X2+\text{X} + 2\text{e}^- \rightarrow \text{X}^{2+}X+2e−→X2+

B

X→X2++2e−\text{X} \rightarrow \text{X}^{2+} + 2\text{e}^-X→X2++2e−

C

X→X2−+2e−\text{X} \rightarrow \text{X}^{2-} + 2\text{e}^-X→X2−+2e−

D

X+e−→X2++e−\text{X} + \text{e}^- \rightarrow \text{X}^{2+} + \text{e}^-X+e−→X2++e−
