Why do elements in the same group have similar physical and chemical properties?
(N/A) The periodic classification is based on the electronic configuration of atoms.
Elements in the same vertical column (group) of the Periodic Table exhibit similar chemical behavior.
This similarity arises because these elements have the same number of valence electrons and the same general distribution of electrons in their outermost orbitals.
