1
Q
ground state
A
the lowest possible energy of an atom
2
Q
hund’s rule
A
electrons occupy orbitals of the same energy in a way that makes the number or electrons with the same spin direction as large as possible
3
Q
Heisenberg
A
it is impossible to know exactly both the velocity and position of a particle at the same time
4
Q

A
an atomic orbital may describe at the most two electrons, each with opposite spin direction
