-
The elements whose last electron enters into any p-orbital are known as p-block elements.
-
The general outer electronic configuration for these elements is ns2np1-6.
-
Group 13 of III A have one electron in p-orbital whereas group 18 or VIII A (inert gas) have 6 electrons in their outer p-orbitals. The outer p-orbitals in an inert gas are fully-filled with electrons.
-
In long form of periodic table, group 1-2 belong to s-block elements, group 13-18 belong to p-block elements and group 3-12 belong to d-block elements.
