Periodic Table is divided into 4 blocks. s – block. Group 1A and 2 A . Alkali metals & Alkaline Earth metals. Valence electrons in S orbitals only. Group 1A, each ecn ends in S1. Group 2A each ecn ends in S2 . p – block. Group 3A to Group 8A of any period. Valence electrons in P1 to P6 orbitals. P sublevel can hold 6 electrons. d- block
