Valence electron - Wikipedia

WebHelium (He) atom (Bohr model) However, the valence electrons of the transition elements may be in the inner orbital. The electron configuration of helium shows that there are a total of two electrons in the last shell of helium. So, the valence electrons of helium are two. Web19 mei 2012 · If you look at hydrogen (H) and helium (He), you will see that do not prefer an eight-electron valence, but a two-electron valence: H forms e.g. H 2, HF, H 2 O, He (which already has two electrons and doesn't form molecules). Web17 feb. 2015 · Explanation: Helium is located in period 1, group 18 of the Periodic Table and has an atomic number equal to 2.
