S1 :One of the many young scientists who chose to throw in their lot with Rutherford was an Oxford physical chemist, Frederick Soddy.
S6:We now know that Gamma rays are a particularly fierce form of X-rays.
P:His association with Rutherford lasted only two years, but that was long enough to change the whole face of physics.
Q:He was just 23.
R:They found that thorium changed into a new element, thorium X, and in the process gave off what was apparently a gas and at the same time a third type of ray, which they named after the Greek letter ‘Gamma’.
S:When he teamed up with Rutherford,they investigated thorium which, as Marie Curie had shown, was radioactive.

Crude mineral oil comes out of the earth as a thick brown or black liquid with a strong smell. It is a complex mixture of many different substances, each with its own individual qualities. Most of them are combinations of hydrogen and carbon in varying proportions. Such hydrocarbons are also found in other forms such as bitumen, asphalt and natural gas. Mineral oil originates from the carcasses of tiny animals and from plants that live in the sea. Over million of years, these dead creatures form large deposits under sea­bed and ocean currents cover them with a blanket of sand and silt. As this material hardens, it becomes sedimentary rock and effectively shuts out the oxygen, thus preventing the complete decomposition of the marine deposits underneath. The layers of sedimentary rocks become thicker, and heavier. Their pressure produces heat, which transforms the tiny carcasses into crude oil in a process that is still going on today.
