What family does cesium belong to?

Group 1A – 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 hydrogen) soft, lustrous, low-melting, highly reactive metals that tarnish when exposed to air.
