As everyone knows chlorofluorocarbons, CFCs for short, have been widely used in the past for fridges and freezers as the refridgerant gas. CFCs contribute to both depleting the ozone layer and they are also greenhouse gases. Due to this their use in the developed world has largely ceased, meaning a good, environmentally friendly replacement is needed. Gadolinium may prove useful to the fridges of the future due to a process known as magnetic refridgeration or adiabatic demagnetisation.
And join Uppingham School's Simon Cotton, to find out how magnetic refridgeration using the ions of gadolinium will be keeping our food cool in the future, in next week's chemistry in its element.

Scandium is a silvery metal that is soft and has a density of about three times that of water. Scandium is a transition metal and is also considered a rare earth element due to similar chemical properties such as difficulty in extracting and in separating from other elements and existence in the same ores, according to Chemicool.
Scandium is the 31 st most abundant element on Earth, according to Periodic Table , with about 22 parts per million abundance by weight in Earth's crust, according to Chemicool. Scandium is scattered thinly and has been found in over minerals.
Within these minerals, scandium is found in its oxide form Sc 2 O 3 , also known as scandia or scandium oxide , according to Scandium Mining. There are many commercial uses for scandium even though the cost of scandium is typically high — several thousand dollars per kilogram for scandium oxide and up to a few hundred thousand dollars per kilogram for pure scandium, according to Chemistry Explained. Russian chemist Dmitri Mendeleev, inventor of the periodic table, predicted the existence and properties of scandium which he called "ekaboron" — similar to boron in , according to the New World Encyclopedia.
All rights reserved. Atomic number. Scandium Scandium is a soft, silvery transition element which occurs in rare minerals from Scandinavia.
It develops a slightly yellowish or pinkish cast when exposed to air. Scandium tarnished in air and burn easily, once it has been ignited. It reacts with water to form hydrogen gas and will dissolve in many acids.
Pure scandium is produced by heating scandium fluoride ScF 3 with calcium metal. Applications Scandium is one of the rare chemicals, that can be found in houses in equipment such as colour televisions, fluorescent lamps, energy-saving lamps and glasses. Scandium in the environment Scandium can rarely be found in nature, as it occurs in very small amounts.
