Solution

Atomic number:
It is defined as the total number of protons present in the nucleus of an atom.
It is represented by the letter ‘Z’.
Mass number:
It is defined as the sum of the total number of protons and neutrons present in the nucleus of an atom.
It is also equal to the sum of the atomic number + the number of neutrons.
It is represented by the letter ‘A’.
The given element consists of 15 protons therefore, the atomic number of the given element is 15.
The number of protons and electrons in a neutral element is equal, therefore, the number of electrons in a given element is equal to 15.
Number of protons given=15 Number of neutrons =16
Since, Mass Number= number of protons + number of neutrons
15 + 16 = 31
Therefore, the mass number of the given element is 31.
