- protons are positive and neutrons are neutral
- a small difference of mass exist
Protons: 6 Neutrons: Anywhere between 2 and 16. The most common isotope of carbon has 6 neutrons.

The normal helium atom has two protons and two neutrons in the nucleus, and two electrons in the "shell".
If you remove 2 protons and 2 neutrons from gold (Au), the resulting element would be platinum (Pt). Gold has 79 protons and 118 neutrons, while platinum has 77 protons and 116 neutrons.
2 protons and 2 neutron
Helium has 2 protons and 2 electrons. He-3 and He-4 isotopes have 1 and 2 neutrons.
A helium atom has 2 protons, 2 neutrons, and 2 electrons.

Yes. He-4 isotope has 2 protons, 2 electrons and 2 neutrons
He is helium: it has 2 protons, 2 electrons and 2 neutrons, only less than 0.001% of He has only 1 neutron (He-3 isotope)
Helium has 2 protons, 2 neutrons, and 2 electrons. The atomic number of helium is 2, which indicates it has 2 protons and 2 electrons in a neutral atom.
