An astrophysicist working at an observatory is interested in finding clouds of hydrogen in the galaxy. Usually, hydrogen is detected by looking for the Balmer series of spectral lines in the visible spectrum. Unfortunately, the instrument that detects hydrogen emission spectra at this particular observatory is not working very well and only detects spectra in the infrared region of electromagnetic radiation. Therefore, the astrophysicist decides to check for hydrogen by looking at the Paschen series, which produces spectral lines in the infrared part of the spectrum. The Paschen series describes the wavelengths of light emitted by the decay of electrons from higher orbits to the n = 3 level.

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.

Consider your answer for the wavelength problem above. What is true about the wavelength of an electron? Small wavelengths never matter. The wavelength is the same size of an atom, so it will influence the properties of the electron as the electron is also very small. The electron produces a very large wavelength that can be picked up in the FM frequency range using a car radio. The wavelength is so small so it doesn't influence the properties of the electron at all.
