List the number of protons electrons and neutrons has helium?
Helium has 2 protons and 2 electrons. He-3 and He-4 isotopes have 1 and 2 neutrons.
How many protons and neutrons and electrons has helium got?
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.
what element 3 protons and 2 electrons?
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^-
What is the number of protons neutrons and electrons for Helium?
protrons=2 electrons=2 neutrons=2
How many protons does heluim have?
Heluim is a gas, used for filling up balloons and is also found in space
What is the symbol for 2 electrons and 2 protons?
Number protons equal to atomic number. So the element is Helium
