Beyond The Bohr Atom

What do the different parts of the de Broglie equation (λ = h / mv) equal?

• h = Planck's constant, m = meters, v = frequency

• h = Planck's constant, m = meters, v = velocity

• h = Planck's constant, m = mass, v = frequency

• h = Planck's constant, m = mass, v = velocity

The Heisenberg Uncertainty Principle states

• velocity and position cannot be determined at the same time
• a beam of light can interfere with the path and speed of an electron
• photons do not affect the position of an electron
• the velocity of a car cannot accurately be measured by a radar beam

Who used theoretical calculations and experimental results to devise and solve a mathematical equation describing the behavior of the electron in a hydrogen atom?

• JJ Thomson

• Niels Bohr

• Erwin Schrodinger

• James Chadwick

Why do we not use Bohr's planetary model today?

• It is too specific; we are not allowed to know the electron's specific location.

• The nucleus was way too large.

• It is too vague; we have more specific information to use now.

• It placed the electrons too close to the nucleus.
