Hydrogen - Element information, properties and uses | Periodic …
It has the lowest density of all gases. Uses. Some see hydrogen gas as the clean fuel of the future – generated from water and returning to water when it is oxidised. Hydrogen-powered fuel cells are increasingly being seen as ‘pollution-free’ sources of …
Lithium - Element information, properties and uses | Periodic Table
Lithium is a soft, silvery-white, metal that heads group 1, the alkali metals group, of the periodic table of the elements. It reacts vigorously with water. Storing it is a problem. It cannot be kept under oil, as sodium can, because it is less dense and floats. So …
Nitrogen - Element information, properties and uses | Periodic Table
Nitrogen is important for plant growth and can be ‘fixed’ by lightning or added to soils in fertilisers. Appearance. A colourless, odourless gas. Uses. Nitrogen is important to the chemical industry. It is used to make fertilisers, nitric acid, nylon, dyes and explosives.
Silicon - Element information, properties and uses | Periodic Table
Uses. Silicon is one of the most useful elements to mankind. Most is used to make alloys including aluminium-silicon and ferro-silicon (iron-silicon). These are used to make dynamo and transformer plates, engine blocks, cylinder heads and machine tools and to deoxidise steel. Silicon is also used to make silicones.
Radium - Element information, properties and uses | Periodic Table
Radium was discovered in 1898 by Marie Curie and Pierre Curie. They managed to extract 1 mg of radium from ten tonnes of the uranium ore pitchblende (uranium oxide, U 3 O 8), a considerable feat, given the chemically methods of separation available to them.They identified that it was a new element because its atomic spectrum revealed new lines.
Oxygen - Element information, properties and uses | Periodic Table
Oxygen. 8. 15.999. Glossary. GroupA vertical column in the periodic table. Members of a group typically have similar properties and electron configurations in their outer shell. PeriodA horizontal row in the periodic table. The atomic number of each element increases by …
Calcium - Element information, properties and uses | Periodic Table
Calcium is a silvery-white, soft metal that tarnishes rapidly in air and reacts with water. Uses. Calcium metal is used as a reducing agent in preparing other metals such as thorium and uranium. It is also used as an alloying agent for aluminium, beryllium, copper, lead and magnesium alloys.
Phosphorus - Element information, properties and uses | Periodic …
Nina Notman. Phosphorus is a non-metal that sits just below nitrogen in group 15 of the periodic table. This element exists in several forms, of which white and red are the best known. White phosphorus is definitely the more exciting of the two.
Caesium - Element information, properties and uses | Periodic Table
Caesium is a soft, gold-coloured metal that is quickly attacked by air and reacts explosively in water. Uses. The most common use for caesium compounds is as a drilling fluid. They are also used to make special optical glass, as a catalyst promoter, in vacuum tubes and in radiation monitoring equipment.
Potassium - Element information, properties and uses | Periodic …
Potassium. 19. 39.098. Glossary. GroupA vertical column in the periodic table. Members of a group typically have similar properties and electron configurations in their outer shell. PeriodA horizontal row in the periodic table. The atomic number of each element increases by one, reading from left to right.
