Sample text

Electron shells The electrons surrounding the atomic nucleus are arranged in energy levels – shells or orbitals. The number of electrons in the outer shell or shells defines an atom’s chemical properties. emission spectrum The spectrum of light frequencies emitted by an element when it is heated. Scientists use the emission spectrum to identify the elements combined in a sample; for example, in an alloy used by the steel industry. Astronomers use the spectrum to identify elements present in distant stars and galaxies.

Oxide Chemical compound in which oxygen combines with another element. polymer Chemical compound that contains long chains, typically of carbon atoms. Polymers are created through a process called polymerization. redox reactions Also called oxidation reduction reactions, chemical reactions in which oxidation and reduction take place. reduction The opposite of the technical meaning of oxidation – that is, a reaction in which one or more electrons is gained. substitution reaction Chemical reaction in which one element in a compound (an atom, ion or group of atoms/ions) is replaced by another element.

Potassium is used in detergents, glass, pharmaceuticals and medical drips. Around 200 tons per year of potassium metal are produced, and most is converted to potassium superoxide. This is used in submarines and space vehicles to regenerate the oxygen in the air when this has become depleted. Superoxide reacts with CO2 to form potassium carbonate and oxygen gas. Potassium is an essential element for living things because, along with sodium, it plays a key role in the operation of the nervous system.
