Question

The characteristics of elements $X,Y$ and $Z$ with atomic numbers, respectively, $33,53$ and $83$ are

• A. $X$ and $Y$ are metalloids and $Z$ is a metal
• B. $X$ is a metalloid, $Y$ is a non-metal and $Z$ is a metal
• C. $X$ and $Z$ are non-metals and $Y$ is a metalloid.
• D. $X,Y$ and $Z$ are metals.

Answer 1

The correct option is B $X$ is a metalloid, $Y$ is a non-metal and $Z$ is a metal

$X(Z=33)=\text{Arsenic is a metalloid}$
$Y(Z=53)=\text{Iodine is a non-metal}$
$Z(Z=83)=\text{Bismuth is a metal}$
Option B is the correct answer.
