Answer:

Explanation:

Lithium has an elemental mass of 6.94 g/mol. It has a density (at 20 degrees C) 0.53 g/cm^3. It melts at 180.5 degrees C and boils at 1342 degrees C. There are two isotopes of it namely Li6 and Li7.

It is the lightest solid metal. It is soft and silvery white colored. It is reactive (not inert). It was discovered in 1817 by Johann Arfvedson.

Standard potential -3.02 V. Ionic radius 0.06 nm. Energy of first ionization approximately 520 kJ/mol.
