If the atomic number of an element is 33, it will be placed in the periodic table in the ____

Options

A. first group
B. third group
C. fifth group
D. seventh group

Answer

C

Explanation

The electronic configuration of element with atomic number 33 is `1s^(2),2s^(2),2p^(6),3s^(2) 3p^(6), 4s^(2),3d^(10),4p^(3)`. As, its last shell have five electrons and hence, its group is 10 + 5 = 15th or VA.
