Common oxidation states of sulfur range from −2 to +6. Sulfur forms stable compounds with all elements except the noble gases. Sulfur polycations, S8 , S4 and S16 are produced when sulfur is reacted with oxidising agents in a strongly acidic solution. The colored solutions produced by dissolving sulfur in oleum were first reported as early as 1804 by C.F. Bucholz, … WebIn a liquid like water, the particles are randomly arranged. They move freely over each other, a bit like marbles in a bucket. This is why liquids can be poured. In a gas, like helium, particles ...
