The characteristics of elements

X, Y

and

Z

with atomic numbers, respectively,

33, 53

and

83

are:

Options

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 $X, Y$ and $Z$ are metals.
D $X$ and $Z$ are non-metals and $Y$ is a metalloid

Correct answer

B. $X$ is a metalloid, $Y$ is a non-metal and $Z$ is a metal.

Step-by-step solution

$X = As 33 \to$ Metalloid

$Y = I 53 \to$ Non-metal
