en.wikipedia.org/wiki/Pauli_exclusion_principleThe Pauli exclusion principle is 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. This principle was formulated by Austrian physicist Wolfgang Pauli in 1925 for electrons, and later extended to all fermions with his spin–statistics theorem of 1940.
www.britannica.com/science/Pauli-exclusion-principlePauli exclusion principle, assertion that no two electrons in an atom can be at the same time in the same state or configuration, proposed (1925) by the Austrian physicist Wolfgang Pauli to account for the observed patterns of light emission from atoms. The exclusion principle subsequently has been generalized to include a whole class of particles of which the electron is only one member.
www.thoughtco.com/definition-of-pauli-exclusion-principle-605486The Pauli exclusion principle states no two electrons (or other fermions) can have the identical quantum mechanical state in the same atom or molecule. In other words, no pair of electrons in an atom can have the same electronic quantum numbers n, l, m l, and m s.Another way to state the Pauli exclusion principle is to say the total wave function for two identical fermions is antisymmetric if ...
chem.libretexts.org/Bookshelves/.../Pauli_Exclusion_PrincipleThe Pauli Exclusion Principle states that, in an atom or molecule, no two electrons can have the same four electronic quantum numbers. As an orbital can contain a maximum of only two electrons, the two electrons must have opposing spins. This means if one is assigned an up-spin ( +1/2), the other must be down-spin (-1/2).
www.sciencedirect.com/topics/.../pauli-exclusion-principleThe Pauli exclusion principle requires that the bare scattering rate given by Eqn. (17) be modified by a factor 1−f m (k′) in the collision integral of the BTE, where f m (k′) is the one-particle distribution function for the state k′ in band (subband) m after scattering.
byjus.com/jee/pauli-exclusion-principlePauli exclusion principle states that in a single atom no two electrons will have an identical set or the same quantum numbers (n, l, m l, and m s). To put it in simple terms, every electron should have or be in its own unique state (singlet state).
courses.lumenlearning.com/physics/chapter/30-9-the-pauli-exclusion-principleThe Pauli exclusion principle says that no two electrons can have the same set of quantum numbers; that is, no two electrons can be in the same state. This exclusion limits the number of electrons in atomic shells and subshells. Each value of n corresponds to a shell, and each value of l corresponds to a subshell.
hyperphysics.phy-astr.gsu.edu/hbase/pauli.htmlPauli Exclusion Principle No two electrons in an atom can have identical quantum numbers.This is an example of a general principle which applies not only to electrons but also to other particles of half-integer spin ().It does not apply to particles of integer spin ().
www.chemicool.com/definition/pauli-exclusion-principle.htmlThe Pauli exclusion principle says that no two identical fermions can simultaneously occupy the same quantum state. The Pauli exclusion principle does not apply to bosons: these are particles that obey Bose-Einstein statistics; they all have integer values of spin. Photons, gluons, gravitons, and the W, Z and Higgs bosons are all bosons.
