Summary - Oxygen and sulphur belong to group VI A. Oxygen shows a valency of -2, while sulphur shows a valency of -2, +4 and +6. Industrially oxygen is manufactured by fractional distillation of liquid air free of dust particles ..

Two scientists, Carl Scheele of Sweden and Joseph Priestly of England working independently, discovered oxygen. They published their discovery in 1777. Scheele obtained oxygen by heating potassium nitrate and mercuric oxide and called it "Fire Air". Priestley called it "Dephlog..

It is absorbed from the soil in the form of sulphate (SO 4 2 - ) though small quantities of sulphur dioxide can be got from the air by foliar absorpti..

Oxides of Sulphur - Two of the important oxides of sulphur are sulphur dioxide and sulphur trioxide. Sulphur dioxide is formed by burning sulphur in air or roasting metal sulphides in the presence of air. A large amount of SO ..
