Summary

Compared to other metals, alkali metals are soft and have low melting points and densities. But they are powerful in other ways. They react violently with water, releasing hydrogen and forming hydroxides, and they tarnish rapidly in dry air. A feature segment on fireworks illustrates the metals' explosive traits while tracing the human affinity for eye-popping, ear-blasting, multicolored displays
