The p-block elements constitute elements belonging to group 13 to 18, and these, together with the s-Block elements, are called Representative elements.
In p-block elements, the last electron enters the outermost p orbital. There are six groups of p–block elements in the periodic table numbering from 13 to 18. Boron, carbon, nitrogen, oxygen, fluorine and helium head the groups. The outer electronic configuration of these elements is ns2 np1.
- Boron is a typical non-metal, and the other members are metals
- Except for F and inert gases, p-block elements show several oxidation states from +n to (n -, 8), where n is the number of electrons present in the outermost shell.
- The p-block elements generally show covalency, but higher members can show electrovalency.
