Electronic Structure - GCSE Physics Definition

Reviewed by: Philippa Platt

Published

Electronic structure refers to the arrangement of electrons in an atom, which is organised in shells or energy levels around the nucleus. Each shell can hold a specific number of electrons: the first shell holds up to 2, the second up to 8, and so on.

Understanding electronic structure is crucial as it determines how atoms interact, bond with other atoms, and participate in chemical reactions.

For GCSE Physics students, grasping this concept helps explain the periodic table arrangement, atomic reactivity, and the principles underlying electronic configurations.
