An orbital can hold at most two electrons, and then only if the electrons have opposite spins. What principle is this?
Pauli exclusion principle
The lowest energy arrangement of electrons in a subshell is obtained by putting electrons into separate orbitals of the subshell with the same spin before pairing electons. Who's rule?
Hund's rule.
A diamagnetic substance has...
Paired electrons
A paramagnetic substance has....
Unpaired electrons
A charge that the electron feels, including both attraction to the nucleus and repulsion from the electrons.
Effective nuclear charge.
Explain first in first out concept for the transition metals:
In transition metals, the s subshell is filled before the d subshell and also removed before the d subshell.
Bonding between two oppositely charged ions.
ionic bond. Example: NaCl
