Question

Which is the correct statement about proton?

• A. Proton is the nucleus of deuterium
• B. Proton is a-particle
• C. Proton is an ionized hydrogen molecule
• D. Proton is an ionized hydrogen atom

Answer 1

The correct option is D

Proton is an ionized hydrogen atom

Explanation for the correct option:

(D) : Proton is an ionized hydrogen atom

• Since hydrogen atoms typically generate one proton and one electron.
• The term "proton" refers to the ionized hydrogen atom that has just one proton remaining.
• The electron is lost when the hydrogen atom is ionized.

Explanation for the incorrect options:

(A) Proton is the nucleus of deuterium

• One proton, one neutron, and one electron make up the hydrogen isotope deuterium.
• A proton and a neutron make up the deuterium atom's nucleus.
• Deuterium is designated by the symbol 2H. Deuterium has an atomic number of 1 and a mass number of 2.

(B) Proton is a-particle

• The proton is a stable subatomic particle.

(C) Proton is an ionized hydrogen molecule

• Proton is an ionized hydrogen atom, not a hydrogen ionized molecule.
• Hydrogen atoms usually generate 1 proton and 1 electron.

Therefore, the correct option is Option (D) : Proton is an ionized hydrogen atom
