Scientists use the periodic table to quickly refer to information about an element, like atomic mass and chemical symbol. The periodic table’s arrangement also allows scientists to discern trends in ...

The Periodic Table is a well-organized chart that contains all 118 known elements in the universe. These elements are the ...

Silicon has changed the world through microelectronic technology. Now optical researchers are getting in on the silicon game too. Look down at your feet. If you dig a little deeper you should ...

Silicon is, after oxygen, the most abundant element of the Earth's crust. But although about 75% of the Earth is made from silica — or silicon dioxide (SiO 2), the main constituent of silicate ...

This is made of aluminium. Aluminium is an element. Now, each element has a chemical symbol made of one or two letters. Cal: Right, OK. And what is the chemical symbol for aluminium? Mrs Roberts ...

Symbol equations are a quick way of representing chemical reactions. They show us what atoms are involved and how they are bonded together. Symbol equations always take the form, reactants → ...

Most organic compounds contain carbon and hydrogen, but they may also include any number of other elements (e.g., nitrogen, oxygen, halogens, phosphorus, silicon, sulfur). Originally limited to the ..

Botanists have long known that adding silicon to soil can help some plants resist certain pests. That led the researchers on this new effort to test whether the chemical element might help ...
