Helium-3 has 1 neutron and 2 electrons.
Helium-4 has 2 neutrons and 2 electrons.
There are particular isotopes that have similar number of electrons and neutrons. Some of these isotopes include hydrogen-2, helium-4, carbon-12 and nitrogen-14.
A helium atom has 2 protons, 2 neutrons, and 2 electrons.
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.
Protons: 2 neutrons: 2 electrons: 2 Helium-3: 2 protons, 1 neutron, 2 electrons Helium-4: 2 protons, 2 neutrons, 2 electrons
Helium has two protons, since its atomic number is two. It is an inert element so it also has two electrons. The number of neutrons depends entirely on the isotope. The most common and stable isotope of Helium has 2 neutrons.
