Question

# The nucleus of the hydrogen atom is called as(A) Neutron(B) Electron(C) Proton(D) Nucleons

Hint: The nucleus of the hydrogen atom consists of only protons in its nucleus since the atomic number, Z=1.

Complete step by step answer: The subatomic particles of an atomic nucleus are neutrons, protons and electrons. Neutrons are neutral particles with no electric charge and a rest mass is equal to ${\text{1}}{\text{.67 x 1}}{{\text{0}}^{{\text{ - 27}}}}$kg. It is represented as$_{\text{0}}{{\text{n}}^{\text{1}}}$.
Electrons are lightest subatomic particle with relative charge -1 with actual mass of ${\text{1}}{\text{.67 x 1}}{{\text{0}}^{{\text{ - 27}}}}$kg. It is represented as $_{\text{0}}{{\text{e}}^{{\text{ - 1}}}}$. The relative mass of an electron is $\dfrac{1}{{1840}}$amu.
Protons are subatomic particles with relative charge +1 with actual mass of ${\text{9}}{\text{.1 x 1}}{{\text{0}}^{{\text{ - 31}}}}$kg. It is represented as $_{\text{0}}{{\text{p}}^{\text{1}}}$.
Nucleons are considered as the atom containing either protons or neutrons. The number of protons present is equal to the number of electrons present in the nucleus.
The atomic number of hydrogen is 1 so the number of electrons and protons present are 1 so the number of neutrons present are 1.
Thus, the nucleus of the hydrogen atom is called nucleons.

So, the correct option is D.

Note: The nucleus is the positively charged core of an atom, which is surrounded by a cloud of negatively charged electrons. Nucleons are particles that the core of an atom consists of, namely positively charged protons and neutral neutrons.
