Question

The element $X$ lies on the left side while the element $Y$ lies on the right side of transition elements. If $X$ and $Y$ are both univalent, then compound formed is likely to be:

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

Answer 1

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

$X$ being univalent is alkali metal and $Y$ being monovalent non-metal is halogen. Therefore, the formula of the compound is $X^{+}{Y}^{-},e.g.,{Na}^{+}{Cl}^{-}$.
