• A. Proton
• B. Neutron
• C. Nucleons
• D. Electrons

Answer 1

The correct option is A

Proton

The explanation for the correct option

(A) Proton

• The atomic number of hydrogen is one. So, the number of protons in hydrogen is one.
• Protons and neutrons are present inside the nucleus of an atom while electrons revolve around in the circular orbits.
• The nucleus of the hydrogen atom contains only one proton and no neutron.
• So, the nucleus of the hydrogen atom is called a proton.

The explanation for the incorrect option

• An electron has a negative charge, while neutrons are uncharged species.
• Protons and neutrons present in the nucleus are collectively known as nucleons.
• The nucleus of the hydrogen atom is called a proton. Hence, options (B), (C), and (D) are incorrect.

Hence, the correct option is (A). The nucleus of a hydrogen atom is called a proton.
