what does Aufbau mean? Aufbau means building up or construction in German
what is the Aufbau principle? This is when electrons are gathered around the nucleus in quantum orbitals or according to a rank in their energies
which energy level do electrons first occupy? they occupy the lowest energy level
what does the Hund rule state? The hund rule states that the lowest energy configuration is the one in which the maximum number of unpaired electrons are distributed among a set of degenerate orbitals
The number of electrons in an atom is equal to the ________ atomic number
How many electrons can fit in the 3d subshell? 10 electrons can fit in the 3d subshell
what is the next subshell after 3d? 4p
List all the orbital subshell in increasing order? 1s<2s<2p<3s<3p<4s<3d<4p<5s<4d<5p<6s<4f<5d<6p<7s<5f<6d<7p
what is madelung's rule? Madelung's rule describes electron configuration and filling of atomic orbitals

Can Aufbau principle be used to predict the elctron configuration of atomss on ionization? Aufbau principle cannot be used to predict electron configuration of atoms on ionization
what does the pauli exclusion principle state? The pauli exclusion principle states that in an atom no two electrons can have the same four electronic quantum numbers
who proposed the pauli exclusion principle? The pauli exclusion principle was proposed by an Austrian physicist called Wolfgang Pauli
The particles that obey the exclusion principle have a characteristic value of ______ spin or intrinsic angular momentum
