Chemical reactions occur when elements or compounds combine and create new compounds. Elements are substances that contain only one type of atom and are represented by unique symbols on the periodic ...

Performing chemical bonding analysis of the Na2He compound, chemists note previously undetected features and predict that, by adding oxygen, a similar compound can be created. Can helium bond with ...

What is an atom? Well, everything is made of atoms! Atoms themselves are made of smaller particles. In this National 4 Chemistry study guide, learn about how elements can join together in different ...

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 ...

Magnesium atoms typically lose two electrons to form chemical compounds. A reactive complex has finally been made in which magnesium keeps all of its electrons, and which can be thought of as a ...

Inorganic elements and their compounds are fundamental to medical biochemistry, serving as essential cofactors in enzymatic reactions, regulators of cellular signalling and metabolism, and ...
