110 Alkali Metals (not worth the time)

Question 1

Physical Properties (name 3)

Answer 1

Flammability:
Differences in electron orbits match several colours in the visible spectrum

Atomic size
Large radii, which means low density and and low metallic bonding. As a result, alkali metals float and are easily cut with a knife.

Electrode Potentials
Very easily oxidized to M+, turning water into OH- and H2
