General Chemistry 1 - Quiz - Early Quantum Theory
Which one of the following types of radiation has the highest wavelength?
Wavelength:
X rays < UV light < visible light < IR light
Which one of the following types of radiation has the highest frequency?
Wavelength:
UV light < IR light < microwaves < radio waves
c = λv ⇒ frequency is inversely proportional to the wavelength
⇒ Frequency:
UV light > IR light > microwaves > radio waves
What is the energy of one photon with a wavelength of 2.25 x 10-2 m?
E =
h = Planck’s constant = 6.626 x 10-34 J.s
c = speed of light = 3.00 x 108 m.s-1
What is the frequency of radiation which has an energy of 1.52 x 106 J per mole of photons?
E = nhv
n = number of photons = 1 mol = 6.022 x 1023 photons
Which statement below is incorrect regarding early quantum theory?
What is the energy of one electron in the second orbital of a hydrogen atom?
En =
En = energy of the orbital n
n = number of the orbital = 2
According to the Bohr model for the hydrogen atom, how is the energy required to excite an electron from n=3 to n=4 compared to the energy required to excite an electron from n=2 to n=3?
