◉ (Ch. 6) How many empty orbitals are present in a single atom of the
element, carbon? Answer: 1
◉ Which of the subshells below do NOT exist due to the constraints
upon the angular momentum quantum number ? Answer: 2d
◉ True or False. If the platinum is irradiated with a beam of UV-A light

that photon is 23 eV? Answer: 5.6 x 10^15
◉ What is the wavelength of light (in nm) emitted from a traffic light
that has a frequency of 5.75 x 1014 Hz? Answer: 522
