Study Notes
Atomic Structure and Properties
- The maximum value of A is n.
Identification of the Element
- +3 indicates an atomic number of 26, which corresponds to Iron (Fe).
Spark and Isotone
- Isotone is related to spark.
Established Principle
- Established: electrons are present, but H+ has no electrons, so Bohr's theory does not apply to H+, but it does to other elements.
Energy Spectrum
- If the electron in a H atom is continuously moving towards the nucleus, the energy spectrum that would be observed is Continuous Spectrum.
Hydrogen Spectrum
- The visible series in the hydrogen spectrum is called the Balmer Series.
Wave-Particle Duality
- The relationship between the wave and particle nature of a microscopic particle is inversely proportional, i.e., as the mass of the particle increases, its wave nature decreases.
Uncertainty Principle
- Heisenberg's Uncertainty Principle is applicable to microscopic particles.
