Question

Element 'X' is strongly electropositive and element 'Y' is strongly electronegative, both are univalent. The compound formed would be:

• A. $X^{+}{Y}^{-}$
• B. $X^{-}{Y}^{+}$
• C. X - Y
• D. $X\to Y$

Answer 1

The correct option is A $X^{+}{Y}^{-}$

A strongly electropositive, univalent 'X' will form an 1 : 1 ionic compound with a strongly electronegative univalent 'Y'.
$X+Y\to X^{+}{Y}^{-}$
