Is Calcium More Reactive Than Barium? Question: Barium is more reactive than calcium because the valence electrons in barium are further away from the nucleus and feel less nuclear attraction, so they require less energy to be removed from the atom. Which element is more reactive than calcium? Alkali metals have got the highest reactivity
What Did Dalton Do For The Atomic Theory? Dalton hypothesized that the law of conservation of mass and the law of definite proportions could be explained using the idea of atoms.
