Electron

Part of Speech

Noun

Pronunciation

/ɪˈlɛktrɒn/ (British English)

/ɪˈlɛktrɑːn/ (American English)

Definitions

1. A subatomic particle with a negative electric charge, found in all atoms and acting as the primary carrier of electricity in solids.
2. A fundamental constituent of matter that orbits the nucleus of an atom.

Usage Examples

• Electrons move around the nucleus of an atom in specific energy levels.
• The flow of electrons creates an electric current in a circuit.

Etymology

From Greek "ēlektron" (ἤλεκτρον), meaning "amber," due to the static electricity effects observed in amber.

Synonyms

• Negatron (in some contexts)
• Beta particle (when moving at high speeds)

Antonyms
