Answer : The element is, Arsenic with atomic number 33 belongs to the group 15.

Explanation :

As we are given that the atomic number of an element is, 33

From the periodic table, we conclude that the element is arsenic that has the atomic number 33.

The element arsenic have symbol (As) belongs to the nitrogen family. The group of nitrogen family is, 15. That means arsenic element belongs to the group 15 and period 4.

The number of electrons in arsenic = 33

The electronic configuration of arsenic is,

1s^22s^22p^63s^23p^64s^23d^{10}4p^3

As we know that if the element belongs to p- block then the group number = no. of valence electrons + 10

In the arsenic the number of valence electrons = 5

Thus, the group number = no. of valence electrons + 10 = 5 + 10 = 15

Hence, the element is, Arsenic with atomic number 33 belongs to the group 15.
