WebHelium is in the 1st period of periodic table so have only 1s orbital. There are two unparallel electrons which are called valence electrons. Step: 2 This step guides to draw helium structure with its atomic symbol ‘He’. The two valence electrons are drawn as dot signs around the symbol. WebWhat is the difference between helium-3 and helium-4? The quantum mechanical effects on helium-3 and helium-4 are significantly different because with two protons, two neutrons, and two electrons, helium-4 has an overall spin of zero, making it a boson, but with one fewer neutron, helium-3 has an overall spin of one half, making it a fermion.
