Lead - Element information, properties and uses | Periodic Table
WEBA dull, silvery-grey metal. It is soft and easily worked into sheets. This easily worked and corrosion-resistant metal has been used for pipes, pewter and paint since Roman times. It has also been used in lead glazes for pottery and, in this century, insecticides, hair dyes and as an anti-knocking additive for petrol.
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.
Oxygen - Element information, properties and uses | Periodic Table
WEBOxygen. 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 one, reading from left to right.
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.
Sodium - Element information, properties and uses | Periodic Table
WEBSodium is the sixth most common element on Earth, and makes up 2.6% of the Earth’s crust. The most common compound is sodium chloride. This very soluble salt has been leached into the oceans over the lifetime of the planet, but many salt beds or ‘lakes’ are found where ancient seas have evaporated.
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.
Antimony - Element information, properties and uses | Periodic Table
WEBAntimony and its compounds were known to the ancients and there is a 5,000-year old antimony vase in the Louvre in Paris. Antimony sulfide (Sb 2 S 3) is mentioned in an Egyptian papyrus of the 16 th century BC. The black form of this pigment, which occurs naturally as the mineral stibnite, was used as mascara and known as khol.The most famous user was the temptress Jezebel whose exploits are ...
Magnesium - Element information, properties and uses | Periodic …
WEBMagnesium is an essential element in both plant and animal life. Chlorophyll is the chemical that allows plants to capture sunlight, and photosynthesis to take place. Chlorophyll is a magnesium-centred porphyrin complex. Without magnesium photosynthesis could not take place, and life as we know it would not exist.
Hydrogen - Element information, properties and uses | Periodic …
WEBIt 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 energy and are now being used in some buses and cars.
