`Mg` and `Li` are similar in their properties due to

A

Same `e//m` ratio

B

same electron affinity

C

Same group

D

Same ionic potential

Text Solution

Verified by Experts

The correct Answer is:
D
`Li^(+)` and `Mg^(+2)` ions have similar polarising power or ionic potential and therefore have similar properties. This type of relationship of the first element of a group with the second element of the next group is known as diagonal relationship.
