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

We identify the elements by their atomic numbers: X has atomic number 33, Y has atomic number 53, and Z has atomic number 83.

Element X (Z = 33) is Arsenic (As). Arsenic is located in Group 15, Period 4. It is classified as a metalloid, as it exhibits properties intermediate between metals and non-metals.

Element Y (Z = 53) is Iodine (I). Iodine is located in Group 17, Period 5. It is classified as a non-metal (a halogen).

Element Z (Z = 83) is Bismuth (Bi). Bismuth is located in Group 15, Period 6. It is classified as a metal, being the heaviest stable element in its group where metallic character increases going down the group.

Therefore, X is a metalloid, Y is a non-metal, and Z is a metal, which corresponds to option (2).
