Its nucleus also contains two neutrons. Since 2 + 2 = 4, we know that the mass number of the helium atom is 4. Finally, the helium atom also contains two electrons since the number of electrons must equal the number of protons.

WebAs the atomic number of helium is 2, it has a total of 2 protons in its nucleus. Thus, the number of protons in Helium is 2. #2 Number of Neutrons in Helium In order to find the number of neutrons of helium atom, you should know its atomic mass first. WebOn the periodic table, hydrogen and helium are the only two elements in the first row, or period, which reflects that they only have electrons in their first shell. Hydrogen and helium are the only two elements that have electrons exclusively in the 1s 1s orbital in their neutral, non-charged, state.
WebHelium is a chemical element. Its official symbol is He, and its atomic number is 2, which means it has two protons in its nucleus.
