position larger than the diameter of the hydrogen atom?
(Assume the diameter of the hydrogen atom is 1.00×10-8
cm.)
Use the Heisenberg uncertainty principle to calculate ?x for a ball
(mass = 132 g, diameter = 6.40 cm) with ?v = 0.205 m/s.
The uncertainty of the (above) ball's position is equal to what...

An excited hydrogen atom could, in principle, have a radius of
1.50 mm .
A - What would be the value of
n for a Bohr orbit of this size? n= ?
B - What would its energy be?
e = ? eV

The Heisenberg Uncertainty Principle can be used to calculate

In the hydrogen atom the radius of orbit B is nine times greater
than the radius of orbit A. The total energy of the electron in
orbit A is -3.40 eV. What is the total energy of the electron in
orbit B?

Answer the following questions using the Bohr model of the
hydrogen atom.
a) A hydrogen atom is the n = 3 excited state when its electron
absorbs a photon of energy 4.40 eV. Draw a diagram roughly to
scale, of relevant energy levels for this situation. Make sure to
show and label the initial energy of the H atom in the n=3 state,
the energy level at which this atom loses its electron, and kinetic
energy of the electron.
b)What...
