Chemistry Assignment Help >> P Block Elements, Characteristics & Properties Assignment Help

The p-block elements are grouped in periodic table having the last six groups excluding helium (located in the s-block). In the p-block elements, the highest energy electron occupies p-orbital. The p-block contains all of the nonmetals (except for Helium and Hydrogen which are s-block elements) and semimetals, as well as some of the other metals.

The p-block groups are following

13 (IIIB, IIIA): Boron group
14 (IVB, IVA): Carbon group
15 (VB, VA): Nitrogen group (or pnictogens)
16 (VIB, VIA): Chalcogens
17 (VIIB, VIIA): Halogens
18 (Group 0): Noble gases (excluding helium)

Properties of p-Block elements: (p block elements contain p-electrons in their valence shell)

P-block elements are non-metals mostly.

These elements have variable oxidation states.

These elements form acidic oxides

These elements form covalent compounds. Halogens form salts with alkali metals

The aqueous solutions their oxides are acidic in nature.

No characteristic colour to the flame

They have high ionization potentials.

They have very large electron gain enthalpies.

State: Solids/liquids/gases at room temperature (Br is liquid)
