Everything we can see and touch, and quite a lot that we can’t as well, is made of tiny particles called atoms. Some substances, like particles of this iron, contain only one kind of atom. Iron is an ...

Elements and Compounds: Understanding elements and compounds is basic knowledge to study chemistry. Elements are the basic building blocks of matter, while compounds are substances formed when two or ...

A chemical compound is a chemical substance consisting of two or more different chemically bonded chemical elements, with a fixed ratio determining the composition. The ratio of each element is ...

The study of elements and compounds is an important part of the science of chemistry. A compound is substance made up of different elements joined together by a chemical bond. Find out more about ...

VOCs, or volatile organic compounds, are compounds that contain carbon atoms and that, at room temperature, easily evaporate. Too small to see and virtually omnipresent both indoors and out, they can ...

A new method to capture carbon dioxide from the air has been developed at the University of Helsinki's chemistry department.

The idea behind the caging technique is that a molecule of interest can be rendered biologically inert (or caged) by chemical modification with a photoremovable protecting group (Fig. 1). Illumination ...

Chemical predictive modelling encompasses empirical computational methods based on observed patterns in data that guide the design of future compounds. Simple physicochemical property-based guidelines ...

There are lots of different substances but only just over a hundred elements. An element is a substance that is made up of only one kind of atom. The atoms in a particular element are the same as each ...
