Why are alkali and alkaline earth metals electropositive?

Elements on the left hand side, i.e. group 1 and 2 a.k.a. alkali and alkali earth metals e.g. lithium, magnesium & co., are more electropositive (shudder) than other elements. But let's join 2010: we say these elements are “less” electronegative. read more

Alkali metals are group 1 element in periodic table i.e., comes under s-block except Hydrogen and are most electropositive in nature. They form strong bonds with the halogens and has strong affinity for them. read more

An alkaline earth metals are six chemical elements in group 2 of the periodic table. They are beryllium (Be), magnesium (Mg), calcium (Ca), strontium (Sr), barium (Ba), and radium (Ra). The elements have very similar properties: they are all shiny, silvery-white, somewhat reactive metals at standard temperature and pressure. read more
