Solved: null Question for NEET

NEET Medium

Magnesium reacts with an element (X) to form an ionic compound. If the ground state electronic configuration of (X) is 1s2 2s2 2p3 , the simplest formula for this compound is

Mg2X

MgX2

Mg2X3

Mg3X2

Step-by-Step Solution

Element ( $X$ ) electronic configuration $1s^2$ $2s^2$ $2p^3$ So, valency of $X$ will be $3$ . Valency of $\text{Mg}$ is $2$ . Formula of compound formed by $\text{Mg}$ and $X$ will be $\text{Mg}_3X_2$ .
