- 12. The major energy levels of an atom.
- 14. A high-speed electron with a -1 charge that is emitted during radioactive decay.
- 15. The arrangement of electrons in an atom, which is prescribed by three rule the aufbau principle, the Pauli exclusion principle, and Hund’s rule.
- 17. A particle of electromagnetic radiation with no mass that carries a quantum of energy.
