If it has 2 protons 2 electrons and 2 neutrons then it's your normal neutral Helium atom.
One atom of helium contains 2 protons and 2 electrons. The most abundant isotope of helium, helium-4, has 2 neutrons. The other, rare isotope of helium, helium-3, has 1 neutron. (Source: Wikipedia)
Protons: 2 neutrons: 2 electrons: 2 Helium-3: 2 protons, 1 neutron, 2 electrons Helium-4: 2 protons, 2 neutrons, 2 electrons
A helium atom has 2 protons, 2 neutrons, and 2 electrons.
The normal helium atom has two protons and two neutrons in the nucleus, and two electrons in the "shell".

Helium has 2 protons and 2 electrons.
Helium has 2 protons, 2 neutrons, and 2 electrons.
Helium has 2 protons and 2 electrons. He-3 and He-4 isotopes have 1 and 2 neutrons.
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.
If it has 2 protons, it has to be Helium. Helium atom has 2 electrons also, so if it has 3 electrons, it would be He^-
protrons=2 electrons=2 neutrons=2
Heluim is a gas, used for filling up balloons and is also found in space
Number protons equal to atomic number. So the element is Helium
