How many protons neutrons and electrons does the inert gas helium have?
2 protons, 2 electrons He-3 isotope has 1 neutron He-4 isotope has 2 neutrons
How many neutrons helium has?
Helium-4 has 2 protons and 2 neutrons. The less common helium-3 has 2 protons but only 1 neutron. There are also several additional isotopes (that is, different number of neutrons), but those are unstable (radioactive).
