Avg score: 90% Most missed: “Which of the following metal is not an alkali metal?”

Group 1A (or IA) of the periodic table are the alkali metals: hydrogen (H), lithium (Li), sodium (Na), potassium (K), rubidium (Rb), cesium (Cs), and francium (Fr).

These are (except for hydrogen) soft, shiny, low-melting, highly reactive metals, which tarnish when exposed to air.
