WS Energy

4. A particle or packet of light energy. A single photon carries a fixed amount of energy that is proportional to its frequency.
5. orbital, A region of space within an atom where there is a high probability of finding an electron. Orbitals have distinct shapes and energy levels.
7. state: The lowest, most stable energy level of an atom, where its electrons are configured closest to the nucleus.
8. effect, A phenomenon in which light shining on a material causes electrons to be ejected. The effect was key to establishing that light is composed of discrete energy packets called photons, rather than being a continuous wave.
10. The ability to do work or cause change. It exists in various forms, such as potential (stored) energy and kinetic (motion) energy.

1. state, A higher energy level than the ground state. An atom reaches an excited state when one or more of its electrons absorbs energy and moves to a higher-energy orbital. This state is unstable and temporary.
2. sublevel, A division within an atom's main energy levels (or electron shells), designated by the letters s, p, d, and f. Each sublevel contains a specific number of atomic orbitals.
3. A form of energy that we can see, which is also referred to as electromagnetic radiation. It behaves as both a wave and a particle (a photon).
6. A specific, discrete amount of energy. In the subatomic world, things like energy and matter exist in minimum-sized packets or units, which are called quanta.
9. A disturbance that transfers energy through a medium (like water or air) or through a vacuum (like light). Waves have properties such as wavelength, frequency, and amplitude.
