The chemical elements present in the modern periodic table are arranged in terms of atomic numbers and chemical periodicity. Periodicity arises from quantum mechanical limitations on how many electrons can occupy various shells and subshells of an atom. The shell model of the atom predicts that a ...

The properties of elements are determined by factors like how easily an electron can be separated from an atom, the bonding power of any given element, the measurement of atomic radius in an element and the attraction of an atom towards an electron from a different element. The diffe...
