Cesium reacts explosively with cold water, and reacts with ice at temperatures above -116 C. Lithium (Li) appears to be the only alkali metal able to form a nitride, although all the alkaline-earth metals form nitrides with the formula M 3 N 2. Cesium Menu.

Gadolinium - Wikipedia

Gadolinium metal is obtained from its oxide or salts by heating it with calcium at 1,450 C (2,640 F) in an argon atmosphere. Sponge gadolinium can be produced by reducing molten GdCl 3 with an appropriate metal at temperatures below 1,312 °C (2,394 °F) (the melting point of Gd) at reduced pressure.
