- These alkali metals are : highly reactive metals ,they are not found freely in nature, they are stored in a mineral oil solution,they have low melting points with low densities with low electronegativity and low ionization.
- They easily react with halogens too.
- They are monovalent metals which forms strong alkaline hydroxides.
