What is lithiums state of matter?
Silvery, soft, low-melting metal that is a good conductor of heat and electricity.
While it is a metal, lithium like the other alkali metals is soft enough to cut with a butter knife. It is about half the density of water, melts at only 180°C, and so, is solid at room temperature.
It forms a body-centred cubic crystal structure.
It is highly reactive, forming an ion of +1 charge in its chemical reactions, which include a fairly vigorous reaction with water, yielding LiOH and hydrogen gas, which is highly combustible.
