Helium has how many protons?
Helium has 2 protons.
What is the number of protons of helium?
Helium is number 2 on the Periodic Table, and the number of its mass is 4. So, therefore it has 2 protons, 2 neutrons, and 2 electrons !
How electrons does a helium atom have?
2 electrons. The atomic number is the number of protons and however many protons there are, that is also the number of electrons.
How many protons are in helium -3?
There are two protons in 3He. All isotopes and ions of the same elements will have the same number of protons regardless of the difference in the number of neutrons or electrons. So the information about which isotope is (by saying helium-3) is unneeded.
How many protons are present in 4He2?
There are two protons present in helium-4 (4He2). The number "2" in the chemical symbol indicates the atomic number, which represents the number of protons in the nucleus of the atom. Helium has an atomic number of 2, hence 2 protons.
Which noble gas has the least number of protons?
Radon (as down a group, the atomic size increases and the ionization energy decreases)
