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 …

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 …
