Question

An element ${}_{11}{X}^{23}$ forms an ionic compound with another element $Y$. Then the charge on the ion formed by $X$ is:

• A. 1
• B. 2
• C. -1
• D. -2

Answer 1

Answer: (A)

1

An ionic bond is formed by the complete transfer of electrons. A bond is formed to attain more stability.

The formation of an octet is the most favorable way to attain stability.

$\to$An element ${}_{11}{X}^{23}$ has $11$ electrons in its natural state.

Configuration:$1s^2,2s^2,2p^6,3s^1$

In the formation of an ionic bond, it will easily donate $3s$ electron and gain $+1$ charge.

The ionic compound formed as $X^{+}{Y}^{-}$

Hence, the correct option is A.
