Science

A subatomic particle with a negative electric charge

Electrons are fundamental particles of matter.

💡 Simply: Imagine tiny little particles zooming around inside everything! These particles, called electrons, carry electricity. They're like the little messengers that make lights turn on or your phone charge.

👶 For kids: A tiny, tiny bit of stuff that's super small and has a little bit of electricity on it. It helps make electricity work!

Idioms & expressions

electron cloud

A model describing the probable location of electrons within an atom.

"The electron cloud represents the region where electrons are most likely to be found."

From Greek *ēlektron* (ἤλεκτρον), meaning "amber." Amber's ability to attract objects when rubbed gave rise to the study of static electricity, and thus the name was adopted for the subatomic particle carrying a negative charge.

The term 'electron' was coined in 1891 by George Johnstone Stoney, initially to describe the 'unit of electricity' responsible for electrolysis. It was later recognized as a particle.

Memory tip

Think of electricity flowing through wires - it's the flow of electrons!
