GENERAL KNOWLEDGE

Detailed explanation-1: -Neutrons are a type of subatomic particle with no charge (they are neutral). Like protons, neutrons are bound into the atom’s nucleus as a result of the strong nuclear force.

Detailed explanation-2: -Neutrons have a neutral electric charge (neither negative nor positive) and have slightly more mass than positively charged protons. “Free” neutrons are those no longer confined inside a nucleus. These free neutrons are produced by nuclear fission and fusion processes.

Detailed explanation-3: -Hydrogen is the only element that does not contain any neutrons in its nucleus.

Detailed explanation-4: -There is only one stable atom that does not have neutrons. It is an isotope of the element hydrogen called protium. Protium, which contains a single proton and a single electron, is the simplest atom. All other stable atoms contain some number of neutrons.

Detailed explanation-5: -The number of electrons in a neutral atom is equal to the number of protons. The mass number of the atom (M) is equal to the sum of the number of protons and neutrons in the nucleus. The number of neutrons is equal to the difference between the mass number of the atom (M) and the atomic number (Z).
