General characteristics of the elements of the 6th group of the main subgroup, common features and differences.

Group 6 consists of the elements oxygen, sulfur, selenium, tellurium and polonium. They can be found in nature in both free and combined states. The Group 6 metals are slightly less electropositive than the previous three Group metals, and the two heaviest metals are substantially the same size due to the reduction of the lanthanides.

Metallic properties increase from oxygen, sulfur, selenium, tellurium to polonium. Electronegativity, ionization energy, a decrease in the affinity of electrons for a group increases with increasing atomic weight.
