Hydrogen, lithium, and sodium each have a valency of one because they possess one electron in their outermost shell, making them capable of losing one electron.
The valency of hydrogen is 1, as it typically gains or loses one electron to achieve a stable electron configuration. Lithium’s valency is 1, and sodium’s is 1, as both elements readily lose their single valence electron.
