13 Nov 2020 The helium atom has two electrons bound to a nucleus with charge Z the minimum energy required to remove the first electron from helium, 

Helium is a simple atom. The nucleus of a helium atom has two protons and two neutrons. Around the nucleus, there are two electrons. The only atom simpler than helium is hydrogen.

Diagram Helium Atom Proton Electric Charge Transparent PNG is a 527x520 In this Bohr-like model of the atom, the two electrons in helium are assumed to  9 Feb 2021 Helium is a chemical element with atomic number 2 which means there are 2 protons and 2 electrons in the atomic structure. One atomic mass  For hydrogen, the atomic mass is 1 because there is one proton and no neutrons. For helium, it is 4: two protons and two neutrons.

Helium-Like Atoms Niels Bohr's model of the atom provided a wonderfully accurate explanation of the spectrum of hydrogen , but when it was applied to the spectrum of helium it failed. Werner Heisenberg developed a modification of Bohr's analysis but it involved half-integral values for the quantum numbers.
