Web14 jan. 2024 · Thus, helium has two valence electrons. Valency of Helium (He) There are many different ways to find out the valency of an atom which reflects the ability of an atom to bond with other atoms. Valence describes how easily an atom or a free radical can combine with other chemical species. Web30 sep. 2024 · The words valence and valency have two related meanings in chemistry. Valence describes how easily an atom or radical can combine with other chemical species. This is determined based on the number of electrons that would be added, lost, or shared if it reacts with other atoms.
