CHM 1151 GENERAL CHEMISTRY I | ACS
CHEMISTRY FINAL EXAM QUESTIONS
AND ANSWERS 100% PASS
Bohr model of the hydrogen atom - ANS 1. electrons in an atom can only occupy certain
orbitals with fixed distance from the nucleus.
2. electrons in permitted orbitals have fixed, specific amount of "allowed" energies.
3. an electron can change energy levels by absorbing energy to move to a higher energy level or
by emitting energy to move to a lower energy level.
de Broglie wavelength - ANS λ = h/mv
Heisenberg principle - ANS it is impossible to know both the position and the momentum of
an electron at the same time
Schrodinger equation - ANS defines the probability of finding an electron
Pauli exclusion principle - ANS each orbital can only hold a max of two electrons with
opposite spins
Aufbau principle - ANS the electrons will occupy the lowest available orbital first
