Detailed explanation-1: -A hydrogen atom is an atom of the chemical element hydrogen. The electrically neutral atom contains a single positively charged proton and a single negatively charged electron bound to the nucleus by the Coulomb force. Atomic hydrogen constitutes about 75% of the baryonic mass of the universe.

Detailed explanation-2: -For example, hydrogen has an atomic number of 1. This means that an atom of hydrogen has one proton, and, if it’s neutral, one electron as well.

Detailed explanation-3: -For example, hydrogen has the atomic number 1; all hydrogen atoms have 1 proton in their nuclei. Helium has the atomic number 2; all helium atoms have 2 protons in their nuclei. There is no such thing as a hydrogen atom with 2 protons in its nucleus; a nucleus with 2 protons would be a helium atom.

Detailed explanation-4: -Hydrogen (H) atoms have 1 proton. Hydrogen atoms with 1 proton and 1 electron are neutral hydrogen (1H1). Hydrogen atoms with 1 proton, 1 electron, and 1 neutron are a heavy isotope of hydrogen called deuterium (2H1). If a proton is added to hydrogen, we then have a different element-helium (4He2).

Detailed explanation-5: -It may be assumed that the electron revolves in a circle of radius 0.53 angstrom (1angstrom=10−10 m and is abbreviated as ∘A with the proton at the centre. Teh hydrogen atom is said to be in the ground state in this case.
