Phosphorus - Element information, properties and uses | Periodic …
WEBNina 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.
Iodine - Element information, properties and uses | Periodic Table
WEBThe radioactive isotope iodine-131 is sometimes used to treat cancerous thyroid glands. Iodine is an essential element for humans, who need a daily intake of about 0.1 milligrams of iodide. Our bodies contain up to 20 milligrams, mainly in the thyroid gland. This gland helps to regulate growth and body temperature.
Argon - Element information, properties and uses | Periodic Table
WEBArgon provides an inert atmosphere in which welded metals will not oxidise. Appearance. Argon is a colourless, odourless gas that is totally inert to other substances. Uses. Argon is often used when an inert atmosphere is needed. It is used in this way for the production of titanium and other reactive elements.
Sulfur - Element information, properties and uses | Periodic Table
WEBSulfur. 16. 32.06. 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.
Beryllium - Element information, properties and uses | Periodic Table
WEBBeryllium is a silvery-white metal. It is relatively soft and has a low density. Uses. Beryllium is used in alloys with copper or nickel to make gyroscopes, springs, electrical contacts, spot-welding electrodes and non-sparking tools. Mixing beryllium with these metals increases their electrical and thermal conductivity.
Mercury - Element information, properties and uses | Periodic Table
WEBMercury. 80. 200.592. 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.
Indium - Element information, properties and uses | Periodic Table
WEBAppearance. A soft, silvery metal that is stable in air and water. Uses. Most indium is used to make indium tin oxide (ITO), which is an important part of touch screens, flatscreen TVs and solar panels. This is because it conducts electricity, bonds …
Chlorine - Element information, properties and uses | Periodic Table
WEBUses and properties. Image explanation. The symbol shows a gas mask. This is because chlorine is a toxic gas, and has been used as a chemical weapon. Chlorine is yellowy-green in colour, as is the image. Appearance. A yellowy-green dense gas with a choking smell. Uses. Chlorine kills bacteria – it is a disinfectant.
Aluminium - Element information, properties and uses | Periodic …
WEBAppearance. Aluminium is a silvery-white, lightweight metal. It is soft and malleable. Uses. Aluminium is used in a huge variety of products including cans, foils, kitchen utensils, window frames, beer kegs and aeroplane parts. This is because of its particular properties.
Nitrogen - Element information, properties and uses | Periodic Table
WEBNitrogen 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.
