Which statement is relating to the spectrum of H atom is false? a)The ...
False Statement:
c) The spectral lines are closer together at longer wavelength
Explanation:
The Spectrum of Hydrogen Atom:
The spectrum of a hydrogen atom is produced when the electrons in the atom undergo transitions between different energy levels. These transitions result in the emission or absorption of electromagnetic radiation, leading to the formation of spectral lines in the hydrogen spectrum.
Quantum Numbers and Spectral Lines:
a) The lines can be defined by quantum number
- Quantum numbers play a crucial role in defining the energy levels and transitions of the hydrogen atom. The principal quantum number (n) determines the energy level of the electron, and different combinations of quantum numbers lead to specific spectral lines in the hydrogen spectrum.
Balmer Series and Wavelengths:
b) The lines of longer wavelength in the Balmer series correspond to the transition between n=3 and n=2 levels
- The Balmer series is a set of spectral lines in the hydrogen spectrum that corresponds to electron transitions between higher energy levels (n>2) and the second energy level (n=2). The lines in the Balmer series have specific wavelengths, and the longer wavelengths correspond to transitions from higher energy levels to the n=2 level.
Continuous Spectrum and Infinite Energy Level:
d) A continuum occurs at n=infinity
- This statement is true. At n=infinity, the energy level of the electron approaches zero, and a continuous spectrum is observed. As the energy level increases towards infinity, the spectral lines become increasingly closely spaced until they merge into a continuous spectrum. This continuum is known as the ionization continuum.
Conclusion:
In conclusion, statement c) "The spectral lines are closer together at longer wavelength" is false. The spectral lines in the hydrogen spectrum are actually closer together at shorter wavelengths. The longer wavelengths correspond to transitions between higher energy levels and the n=2 level, resulting in specific lines in the Balmer series. On the other hand, a continuum occurs at n=infinity, where the spectral lines merge into a continuous spectrum.
