Helium has two electrons as its atomic number is 2.
the number of electrons found in the third shell of an helium atom are nill because its atomic number is 2
2 electrons. The atomic number is the number of protons and however many protons there are, that is also the number of electrons.
By definition, one mole would be the same as the atomic mass. You take the number of moles and multiply it by the atomic mass (divide by one mole for units to cancel). So if you have just 1 mole, the number of grams will be the atomic mass. Helium's atomic mass is 4.003 grams.
Helium has a standard atomic weight of 4.0026 atomic mass units (amu).
The atomic number of the element Helium is two.

There are 2 protons in a helium atom. Helium is the second lightest element on the periodic table, with an atomic number of 2, indicating the number of protons in its nucleus.
The number of protons the specific element has. Example, Hydrogen has 1, Helium has 2, Lithium has 3...etc etc etc Not to be confused with atomic mass.
