Niels Bohr - GCSE Chemistry Definition

Reviewed by: Richard Boole

Last updated

Niels Bohr was a Danish scientist who made key contributions to our understanding of atomic structure. He is best known for developing the Bohr Model of the atom. In this model, electrons move around the nucleus in fixed energy levels (or shells), rather than randomly.

This idea helped explain why atoms form chemical bonds in certain ways. Bohr’s work improved earlier models like the Nuclear Model and helped shape the modern atomic theory taught in GCSE Chemistry.

Expertise: Chemistry Content Creator

Richard has taught Chemistry for over 15 years as well as working as a science tutor, examiner, content creator and author. He wasn’t the greatest at exams and only discovered how to revise in his final year at university. That knowledge made him want to help students learn how to revise, challenge them to think about what they actually know and hopefully succeed; so here he is, happily, at SME.
