Answer:
Option b. 32S
Explanation:
Given:
No. of protons = 16
No. of neutrons = 16
Atomic number of an element is equal to the number of protons present in it.
Therefore, atomic number of the element = 16
Mass number of the element is equal to sum of number of protons and neutrons.
Therefore, Mass number = 16 + 16 = 32
Element 'S' has atomic number 16 and its mass number is 32.
So among the given options, option b is correct.
