Four blocks of elements in the periodic table. 1 –  s block elements. Elements of groups 1 and 2 each possessing one and two electrons respectively in the  s orbital of their outermost orbits are together known as  s block elements. Example :                 Na:  1s2 2s2 2p6 3s1                   Mg:  1s2 2s2 2p6 3s2 Characteristics of s block elements. a -They …

Shapes  of s and p orbitals s orbital can have only one possible orientation (as it’s m quantum is zero), it is spherical in shape i.e., in an s orbital the electron distribution is symmetrical around the nucleus in all directions. However the size of s orbital depends on principal quantum number. Large n means large size. Thus 3s orbital …
