- PCAT Question of the Day
In the Bohr model of the atom, electrons jump to a higher energy orbital when:
A) sufficient energy is absorbed
B) their spin coefficient increases sufficiently
C) they move to a smaller radius orbital
D) photons are given off
Click for Explanation
The Bohr model of the atom suggested that electrons existed in orbitals of finite energy levels. Electrons may jump to a higher orbital if sufficient energy in the form of photons is absorbed, and finite energy is given off in the form of photons if an electron in a higher energy orbital returns to a lower level orbital.
A) sufficient energy is absorbed, correct
B) their spin coefficient increases sufficiently, incorrect, there is no spin coefficient
C) they move to a smaller radius orbital, incorrect, electrons gaining energy move to larger radius orbitals
D) photons are given off, incorrect, photons are given off when electrons move to lower energy orbitals
