Question

An atom has an atomic number of 15 and a mass number of 31. How many protons are there in the atom?

Answer 1

No of protons = 15

Step-by-step explanation:

Given that,

Atomic number = 15

Mass number = 31

We need to find the no of protons in the atom.

We know that,

No of protons = Atomic no of the atom

No of protons = 15

Hence, there are 15 protons in the atoms.
