Study Notes
Hydrogen-Like Ion
- The ion is a hydrogen-like ion with a charge of +2. The symbol "zX+2" indicates that the ion has a charge of +2, where z represents the atomic number of the element X.
- The energy of ionization (Eni) for the ion is 30.6 eV.
- The electron transitions to the n = 4 level.
- The Rydberg constant (R) is 1.09677 x 107 m-1, which is a fundamental constant in atomic spectroscopy.
- The speed of light (c) is 3 x 108 m/s.
- Planck's constant (h) is 6.63 x 10-34 J·s, which relates the energy of a photon to its frequency.
Transition Calculations
- The frequency of the radiation corresponding to the transition can be calculated using the Rydberg formula and the given constants.
- The transition can be either an emission or absorption process based on the energy levels involved:
- Emission occurs when an electron transitions from a higher energy level to a lower energy level, releasing energy as a photon.
- Absorption occurs when an electron transitions from a lower energy level to a higher energy level, absorbing energy from a photon.
Problem Analysis
- To determine the charge Z and the initial energy level n1, the energy of ionization must be utilized, along with the Rydberg formula.
- The Rydberg formula can also be used to calculate the frequency of the radiation corresponding to the transition.
- By analyzing the change in energy levels, it can be determined whether the transition is an emission or absorption process.
