Question

For triply ionized beryllium calculate the.
energy
of the photon with the longest wavelength
in
the Balmer
series.

Expert Solution

Concept and Principle:

The Bhor theory can be used to study atoms with one electron. When an atom gets ionized it will lose electrons thus an atom with a higher Z which has only one electron left after ionization can be studied using Bohr's model.

The energy of the n^th state of such an atom is given by,

$E_{n} = - (13 .6 eV) \frac{Z^{2}}{n^{2}}$

Here Z is the atomic number.

The structure is 828 m (2,716.5 feet) and has more than 160 stories. A tourist is obviously using the elevator to reach their hotel room and after a long ride finally arrives at the correct floor where the tourist has -189000 J of potential energy. If the 181 lb tourist has zero potential energy at the top of the building, what is the height h of the hotel room above the ground? The acceleration due to gravity is 9.81 m/s². h =
