Li(s) Floats, fizzes gently, melts, slow H₂ release.
K(s) I.gnites instantly, lilac flame, melts, moves quickly, violent
Rb(s) Explosive, red-violet flame, fast, exothermic, may splatter.
Na(s) Floats, melts, fizzes rapidly, yellow flame, H₂ ignites.
Cs(s) Extremely violent, explosion, bright flash, blue flame, instant ignition.
