in-depth chemistry contentconcepts
What is an Atom
Protons, neutrons and electrons, and the models from Dalton to quantum — the building block of all matter.
concepts
What are Isotopes
Same element, different neutrons — stable vs radioactive isotopes, and why atomic masses are decimals.
concepts
What is Radioactivity
How unstable atoms decay — Becquerel, Marie Curie, alpha, beta and gamma radiation, and half-life.
concepts
What is Chemical Bonding
Why atoms bond, and how electrons build ionic, covalent and metallic bonds — the glue of all matter.
history · safety
The Chernobyl Disaster
The flawed RBMK reactor, the 1986 explosion and the radioactive fallout that reshaped nuclear safety.
history · safety
The Bhopal Disaster
The chemistry of methyl isocyanate and history's worst industrial tragedy — including Mother Teresa's visit to the survivors.
concepts
What is the Periodic Table
How the 118 elements are organised, the history from Mendeleev to Moseley and the trends that give the table meaning.
