Definition of «electron»

An electron is a subatomic particle that carries a negative electric charge. It is one of the fundamental particles that make up matter and plays an important role in various chemical reactions, as well as in electrical conductivity and magnetic properties.

Usage examples

  1. Electrons are negatively charged particles that orbit around the nucleus of an atom.
  2. The movement of electrons between atoms is responsible for the formation of chemical bonds.
  3. In electrical circuits, electrons flow from the negatively charged terminal of a battery to the positively charged terminal.
  4. The behavior and arrangement of electrons determine an element's chemical properties and reactivity.
  5. Electrons play a crucial role in the transfer of energy, such as in the process of photosynthesis where electrons are excited by light.
  6. Electrons are involved in various technological devices like television screens, computer chips, and solar cells.
  7. Electrons can be gained or lost during chemical reactions, leading to the creation of ions with different charges.
  8. The concept of electron configuration explains the distribution of electrons in different atomic orbitals.
  9. The deflection of electrons in a cathode-ray tube led to the discovery of their existence by J.J. Thomson.
  10. Electrons are also involved in the production of X-rays and their control is essential in radiation therapy.
