MCQ

Most elements are solids at $25^\circ C$ and $1$ atm pressure, the exception being the $11$ elements that are gases and $2$ that are liquids. What $2$ elements are liquids?

✓
$\ce{Hg}$ and $\ce{Br}$
B
$\ce{Hg}$ and $\ce{I}$
C
$\ce{Ag}$ and $\ce{Kr}$
D
$\ce{Ag}$ and $\ce{Kr}$

✓

Answer

Correct option: A.

$\ce{Hg}$ and $\ce{Br}$

At room temperature, that is $25^\circ C$ and $1$ atm, Mercury and Bromine both exist as liquids. Hence option A gives the correct pair.
