What is the number of protons in the nucleus of an atom equivalent to? number of neutrons atomic number mass number atomic weight

atomic number

Explanation:

Atomic number is defined as the number of protons or number of electrons that are present in an atom.

Atomic number = Number of electrons = Number of protons

Mass number is defined as the sum of number of protons and neutrons that are present in an atom.

Mass number = Number of protons + Number of neutrons

Atomic weight is the weight of an atom. It is equal to the number of protons and neutrons, with a little extra added by the electrons.

Thus the number of protons in the nucleus of an atom equivalent to atomic number

the energy to form plasma comes from heat or electricity in the atmosphere!
