Lithium is a very soft silvery metal, and can be cut with a knife just like butter. Lithium tarnishes quickly in the air, and will turn black within seconds. It is the lightest metal. Its density is only 0.53 g/cm^3, about the same as pine wood. Lithium is light enough to float in water.
Lithium is unique in the Group because it also reacts with the nitrogen in the air to form lithium nitride (again, see below). Lithium burns with a strongly red-tinged flame if heated in air. It reacts with oxygen in the air to give white lithium oxide. With pure oxygen, the flame would simply be more intense. For the record, it also reacts with the nitrogen in the air to give lithium nitride. Lithium is the only element in this Group to form a nitride in this way.
