Magnesium reacts with an element (X) to ...

Magnesium reacts with an element (X) to form an ionic compound. If the ground state electronic configuration of (X) is `1s^(2),2s^(2)2p^(3)`, the simplest formula for this compound is

A

`Mg_(2)X_(3)`

B

`MgX_(2)`

C

`Mg_(2)X`

D

`Mg_(3)X_(2)`

Text Solution

Verified by Experts

The correct Answer is:
D
`Mg^(2+) X^(+3) ` i.e., `Mg_(3)X_(2)`
Thus , option (d) is correct .
