Chemical bonding

In this collection we explore the fundamental principles of chemical bonding, covering covalent, ionic, and metallic bonding, as well as molecular structure, intermolecular forces, and the role of chemical bonding in shaping the properties and behaviour of molecules.


Mechanical bonding

The mechanical side of bonding


Synthetic chemists are finally mastering the assembly of interlocked molecules held together by the mechanical bond, find James Mitchell Crow

Weak bonding

Reaching into the non-covalent toolbox


Alongside supramolecular stalwarts, budding bonding forms are vying to be valuable, finds Andy Extance

Bonds under pressure

When a bond gets too extreme


Chemical bonds are part of the way chemists rationalise the behaviour of atoms in the conditions of the world around them. Tim Wogan looks at how they are affected when those conditions change

Do bond classifications help or hinder chemistry?


Ionic, covalent, metallic and more… but there’s debate about whether bonds are real at all

What is a bond?


There’s more to bonding than covalent, ionic and the lines we draw between atoms on paper. Philip Ball takes on the expanding list of chemical connections
