Group 16 (Oxygen group) elements

Elements belonging group 16 are called chalgogens or ore forming elements as most of the ores are oxides or sulphides.

Group 16 (Oxygen group) elements:

Occurrence:

Elements belonging group 16 are called chalgogens or ore forming elements as most of the ores are oxides or sulphides. First element oxygen, the most abundant element, exists in both as dioxygen in air (above 20 % by weight as well as volume) and in combined form as oxides. Oxygen and sulphur makes up about 46.6 % & 0.034 & of earth crust by weight respectively. Sulphur exists as sulphates (gypsum, epsom etc...) and sulphide (galena, Zinc blende etc...). It is also present in the volcanic ashes. The other elements of this groups are scarce and are often found as selenides, tellurides etc... along with sulphide ores.

 

Physical properties:

The common physical properties of the group 16 elements are listed in the Table.
