Period 3 element phosphorus originates from oxidation of the white (but not red) phosphorus and should be called chemiluminescence. It is also the lightest element to easily produce stable exceptions to the octet rule. The vast majority of phosphorus compounds are consumed as fertilizers. Other applications include the role of organophosphorus compounds in detergents, pesticides and nerve agents, and matches. "Sulfur" (symbol S) is an abundant, multivalentnon-metal. Under normal conditions, sulfur atoms form cyclic octatomic molecules with chemical formula S. Elemental sulfur is a bright yellow crystalline solid when at room temperature. Chemically, sulfur can react as either an oxidant or reducing agent.
Red or Black? their colour revealed is the winner and advances to the new final round, "The Vortex". The Vortex is "a true test of skill, nerve and judgment". It consists of a "mini velodrome" which flashes between red and black at a constant rate. The aim is to watch the sequence and adjust the power of the launcher, which will fire a ball into The Vortex. If the balls lands in the End Zone in the contestant's chosen colour, they win the jackpot (starting at £500,000), or else it will increase by £500,000 for the next show.
