Quantum Mechanics Theory
: the distribution of electrons within the permissible
The subshells can be arranged in order of increasing energy as:
1s, 2s, 2p, 3s, 3p, 4s, 3d, 4p, 5s, 4d, 5p, 6s, 4f, 5d,….
The max. #
of electrons in an s, p, d, and f subshell are 2, 6, 10, and 14
, an atom’s electrons occupy the lowest-energy subshells
consistent with the Pauli exclusion principle.
subshell tends to be the most stable state:
