Reactions

About the book

In Reactions, Peter Atkins opens the door to what usually remains invisible: the intimate lives of atoms as they leave old partners, form new bonds, exchange protons, surrender electrons, reorganise themselves and give rise to new forms of matter. Chemistry ceases to be a remote collection of formulas and becomes a microscopic theatre of encounters, ruptures, seductions, collisions, alliances and transformations — from simple precipitation to the processes sustaining life.

The book first assembles a fundamental toolkit: precipitation, neutralisation, combustion, reduction, redox reactions, electrolysis, electrochemistry, corrosion, catalysis and chemical substitution. Each reaction is presented as a molecular scene in motion, where atoms and molecules seem to act with small chemical ‘personalities’: some give, others receive; some attract, others repel; some resist, others yield. From this invisible choreography arise salts, metals, energy, rust, electric current, materials and new substances.

Atkins then takes these tools into a more complex workshop, where chemistry becomes deliberate construction: polymerisation, synthesis, enzyme action, photochromism, vision, atmospheric photochemistry and photosynthesis. What seemed confined to the laboratory reveals itself as the living world: light at work in leaves, electrons powering metabolism, enzymes cutting and assembling molecules, modern materials emerging from carefully directed atomic architectures.

Reactions is an immersive journey inside chemical transformation. It shrinks us to molecular scale to watch matter reinvent itself from within — in flasks, flames, batteries, metals, cells, plants and thought itself. A brief, visual and powerful introduction to the secret workshop where atoms change their destiny and the world quietly remakes itself.
