A ground state H-atom absorbs a photon of wavelength 94.91 nm, and its electron attains a higher energy level. The atom then emits two photons: one of wavelength 1281 nm to reach an intermediate level, and a second to return to the ground state. a. What higher level did the electron reach? (Ans. n = 5) b. What intermediate energy level did the electron reach? (Ans. n =3) c. What was the wavelength of the second photon emitted? (Ans. 1.02 x 107 m)
Atomic Structure
The basic structure of an atom is defined as the component-level of atomic structure of an atom. Precisely speaking an atom consists of three major subatomic particles which are protons, neutrons, and electrons. Many theories have been stated for explaining the structure of an atom.
Shape of the D Orbital
Shapes of orbitals are an approximate representation of boundaries in space for finding electrons occupied in that respective orbital. D orbitals are known to have a clover leaf shape or dumbbell inside where electrons can be found.
The Rydberg's equation for the electronic transition in the H atom is as follows:
Here:
c is the velocity of light.
is the wavelength of the radiation or photon.
RH is the Rydberg's constant with value 2.18 x 10-18J.
ni is the initial state of the electron/lower level.
nf is the final state of the electron/higher level.
