Element `X` is strongly electropositive and element `Y` is strongly electronegative. Both are univalent. The compound formed would be

Options

A. `X^(+)Y^(-)`
B. `X^(-)Y^(+)`
C. `X-Y`
D. `X to Y`

Answer

A

Explanation

Strongly electropositive, univalent X will form an 1 : 1 ionic compound with strongly electronegative, univalent `Y. X+Y to X^(+)Y^(-)`
