The atomic number of an atom equals the number of electrons orbiting the nucleus.
Answer: Option

The atomic number of an atom is equals to the :.
1) number of protons and not number of electrons when the atom is charged;.
2) if the atom is neutral, then the atomic number is equals to the protons and electrons both, because they are equal.

The atomic nos is the nos of protons in the nucleus. Protons are inside the nucleus it is not orbiting the nucleus. Nucleus consist of protons and neutrons.
Protons +ve charge.
Electrons -ve charge.
Nutrons no charge.
Protons +ve charge.
Electrons -ve charge.
Nutrons no charge.

Atom is supposed to be neutral so No of electrons should be equal to the number of protons. Isnt it? Then the statement is supposed to be true.
Please correct me if I'm wrong.

Once charged it is known as ion and not atom. When we say atom it means it is neutral and always number of protons is equal to number of electrons in any atom.
