DETAILED SOLUTIONS GRADED A+
◉ de Broglie wavelength. Answer: λ = h/mv
◉ Heisenberg principle. Answer: it is impossible to know both the
position and the momentum of an electron at the same time
◉ Schrodinger equation. Answer: defines the probability of finding
an electron
◉ Pauli exclusion principle. Answer: each orbital can only hold a
max of two electrons with opposite spins
◉ Aufbau principle. Answer: the electrons will occupy the lowest
available orbital first
◉ Hund's rule. Answer: when filling orbitals that have the same
energy, fill orbitals singly before pairing with another electron
◉ law of conservation of energy. Answer: energy is neither created
nor destroyed; it can be transferred from one form to another.
the total energy in a chemical system is unchanged.
