Uses and Properties:

• Gadolinium is a bright, soft, silvery-white metal that is both ductile and malleable.

• It is one of the rare earth metals.

• It does not react in dry air but will tarnish to a flaky white oxide in moist air that does not protect it from further oxidation.

• The metal reacts slowly with water and is soluble in dilute acid.

• A soft, silvery metal that reacts with oxygen and water.
