- 2E͎l͎e͎c͎t͎r͎o͎n͎ C͎o͎n͎f͎i͎g͎u͎r͎a͎t͎i͎o͎n͎is the distribution of electrons of an atom or molecule (or other physical structure) in atomic or molecular orbitals.
- 3E͎l͎e͎c͎t͎r͎o͎n͎ O͎r͎b͎i͎t͎a͎l͎s͎is a mathematical function that describes the wave-like behavior of either one electron or a pair of electrons in an atom.
- 4H͎u͎n͎d͎'s͎ R͎u͎l͎e͎refers to a set of rules that German physicist Friedrich Hund formulated around 1927, which are used to determine the term symbol that corresponds to the ground state of a multi-electron atom. The first rule is especially important in chemistry, where it is often referred to simply as Hund's Rule.
- 5O͎r͎b͎i͎t͎a͎l͎ D͎i͎a͎g͎r͎a͎m͎are pictorial descriptions of the electrons in an atom.
- 6P͎a͎u͎l͎i͎ E͎x͎c͎l͎u͎s͎i͎o͎n͎ P͎r͎i͎n͎c͎i͎p͎l͎e͎s the quantum mechanical principle which states that two or more identical fermions (particles with half-integer spin) cannot occupy the same quantum state within a quantum system simultaneously.
- 7Q͎u͎a͎n͎t͎u͎m͎ N͎u͎m͎b͎e͎r͎describe values of conserved quantities in the dynamics of a quantum system.
- 8S͎p͎i͎n͎is one of two types of angular momentum in quantum mechanics, the other being orbital angular momentum.
- 9E͎l͎e͎c͎t͎r͎o͎n͎a stable subatomic particle with a charge of negative electricity, found in all atoms and acting as the primary carrier of electricity in solids.
- 10E͎n͎e͎r͎g͎y͎ L͎e͎v͎e͎l͎The term is commonly used for the energy levels of electrons in atoms, ions, or molecules, which are bound by the electric field of the nucleus, but can also refer to energy levels of nuclei or vibrational or rotational energy levels in molecules.
- 11N͎e͎u͎t͎r͎o͎n͎a subatomic particle of about the same mass as a proton but without an electric charge, present in all atomic nuclei except those of ordinary hydrogen.
- 12N͎u͎c͎l͎e͎u͎s͎the positively charged central core of an atom, consisting of protons and neutrons and containing nearly all its mass.
- 13O͎r͎b͎i͎t͎It is well-defined circular path followed by electron around nucleus.
- 14O͎r͎b͎i͎t͎a͎l͎are regions of space around the nucleus of an atom where an electron is likely to be found.
- 15P͎r͎o͎t͎o͎n͎a stable subatomic particle occurring in all atomic nuclei, with a positive electric charge equal in magnitude to that of an electron, but of opposite sign.
- 16S͎u͎b͎a͎t͎o͎m͎i͎c͎ P͎a͎r͎t͎i͎c͎l͎e͎are particles much smaller than atoms. The two types of subatomic particles are: elementary particles, which according to current theories are not made of other particles; and composite particles.
- 17V͎a͎l͎e͎n͎c͎e͎ E͎l͎e͎c͎t͎r͎o͎n͎s an outer shell electron that is associated with an atom, and that can participate in the formation of a chemical bond if the outer shell is not closed; in a single covalent bond, both atoms in the bond contribute one valence electron in order to form a shared pair.
- 18★彡 Energy 彡★is a conserved quantity; the law of conservation of energy states that energy can be converted in form, but not created or destroyed.
- 19★彡 Frequency 彡★is the number of occurrences of a repeating event per unit of time.
- 20★彡 Hertz 彡★is the SI derived unit, with a special name, for frequency. The hertz is the frequency of a periodic phenomenon of which the period is one second (Hz = 1 s-1).
- 21★彡 Wavelenght 彡★the distance between successive crests of a wave, especially points in a sound wave or electromagnetic wave.
