Question:

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

1. $\mathrm{X}$ and $\mathrm{Y}$ are metalloids and $\mathrm{Z}$ is a metal.

2. $\mathrm{X}$ is a metalloid, $\mathrm{Y}$ is a non-metal and $\mathrm{Z}$ is a metal.

3. $\mathrm{X}, \mathrm{Y}$ and $\mathrm{Z}$ are metals.

4. $\mathrm{X}, \mathrm{Y}$ and $\mathrm{Z}$ are metals.

Correct Option: , 2

Solution:

$\mathrm{X}={ }_{33} \mathrm{As} \rightarrow$ Metalloid

$\mathrm{Y}={ }_{53} \mathrm{I} \rightarrow$ Nonmetal

$\mathrm{Z}={ }_{83} \mathrm{Bi} \rightarrow$ Metal
