leelismetallide
Leelismetallide refers to a class of chemical compounds formed between alkali metals and elements that are more electronegative. These compounds are characterized by the alkali metal atom donating its valence electron to the more electronegative element, resulting in a compound where the alkali metal exists as a cation and the other element has a negative charge. Examples include lithium hydride (LiH), sodium chloride (NaCl), and potassium sulfide (K2S).
In leelismetallides, the alkali metal, such as lithium, sodium, potassium, rubidium, or cesium, typically forms ionic
