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

Options

  1. AX and Y are metalloids and Z is a metal
  2. BX is a metalloid, Y is a non-metal and Z is a metal.
  3. CX , Y and Z are metals.
  4. DX 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 → Metalloid Y = I 53 → Non-metal Z = Bi 83 → Metal
