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

1. X and Y are metalloids and Z is a metal.
2. X is a metalloid, Y is a non-metal and Z is a metal.
3. X, Y and Z are metals.
4. X and Z are non-metals and Y is a metalloid

Correct answer: X is a metalloid, Y is a non-metal and Z is a metal.

Solution

Element X (atomic number 33) is arsenic, a metalloid; element Y (atomic number 53) is iodine, a non-metal; and element Z (atomic number 83) is bismuth, a metal. This classification aligns with the periodic table's categorization of these elements based on their properties.
