ATOMIC PHYSICS

s, p, d,f stands for

“sharp,” “principal,” “diffuse,” and “fundamental,”

parts of periodic table

periods(rows), blocks(columns) and groups(columns)

difference between blocks and groups

groups are linked ot valence electrons

state the quantum numbers

principal (n), angular (l), magnetic (ml) and spin (ms)

state the possible values of all 4 quantum numbers

recite/write the electron configuration

recite mo <3

what is the purpose of quantum numbers?

solving S.E. gives rise to qunatum numbers, which describe the behavior of quantum systems

when S.E. is solved using radial coordinates, it gives rise to two qunatum numbers, which are _____ and _____

principal and azimuthal/angular

when S.E. is solved using azimuthal coordinates, it gives rise tothe qunatum number

magnetic quantum number

the Pauli exclusion principle created by _________ states that _______

Wolfgang Pauli, no two electrons in the same atom can have identical values for all four of their quantum numbers

explain the zeeman effect

when an electron has a non-zero angular momentum (l), they have a magnetic dipole moment due to the electron motion. Hence these states are affected if the atom is placed in a magnetic field

who confirmed the existence of an electron spin?

Otto Stern and Walther Gerlach, Stern-Gerlach experiment 1921

(Quantum Numbers) total energy of an atom depends on?

principal qunatum number (n)

(Quantum Numbers) related to magnitude of angular momentum

orbital quantum number (l)

(Quantum Numbers) direction of elctron’s angular momentum

magnetic quantum number (ml)

(Quantum Numbers) only has tow values +1/2 or -1/2, its presence is a relativistic effect

magnetic spin (ms)

who modified schrodinger’s orig theory to contain magnetic spin?

Paul Adrien Maurice Dirac
