WebJan 29, 2024 · Valency can be defined as the combining capacity of an atom. It describes the number of bonds that one atom can form with another compatible atom. This concept arises from Niel Bohr’s model of the atom. The combining capacity, or affinity of an atom of a given element is determined by the number of hydrogen atoms that it combines with. WebFor example, the n = 5 to n = 2 transition emits blue light which is higher in energy (shorter wavelength) than the red light that is emitted when the electron falls from the n = 3 to the n = 2 level. ...
