Chemical Bonding - Result Question 110
####9. Element $X$ is strongly electropositive and element $Y$ is strongly electronegative. Both are univalent. The compound formed would be
(1980, 1M)
(a) $X^{+} Y^{-}$
(b) $X^{-} Y^{+}$
(c) $X-Y$
(d) $X \rightarrow Y$
Show Answer
Answer:
Correct Answer: 9. (a)
Solution:
- Strongly electropositive, univalent $X$ will form an $1: 1$ ionic compound with strongly electronegative, univalent $Y$.
$$ X+Y \longrightarrow X^{+} Y^{-} $$
