On the basis of Rutherford’s model of an atom, which subatomic particle is present in the nucleus of an atom?

According to Rutherford’s model of an atom, the positively charged protons are present in the nucleus of an atom.

The atomic number of a chemical element is the number of protons found in the nucleus of every atom of that element. The atomic number uniquely identifies a chemical element.

The mass of a proton is 1.673 × 10^-27 kg and charge on the proton is +(1.6 x 10^-19) Coulomb.
