Question

Write short notes on electronic configuration, oxidation state and general comparative study of group-16 elements.​

Answer 1

Electric configuration: The electron configuration of an element describes how electrons are distributed in its atomic orbitals.

Oxidation State: The oxidation state, sometimes referred to as oxidation number, describes the degree of oxidation (loss of electrons) of an atom in a chemical compound.

General comparative study of group-16 elements: Metallic character increases down the group, with tellurium classified as a metalloid and polonium as a metal. Melting point, boiling point, density, atomic radius, and ionic radius all increase down the group. Ionization energy decreases down the group.
