Lanthanum | chemical element | Britannica
Lanthanum is a ductile and malleable silvery white metal that is soft enough to be cut with a knife. It is the second most reactive of the rare-earth metals after europium.Lanthanum oxidizes in air at room temperature to form La 2 O 3.It slowly reacts with water and quickly dissolves in diluted acids, except hydrofluoric acid (HF) because of formation of a protective fluoride (LaF 3) layer on
