In photoelectron spectroscopy, an electron is ejected from an atom by the collision of a UV photon with the surface of the atom. The equation describing this reaction is similar to the photoelectric effect described by Einstein: hv = ½ mv + Ei, where E; is the ionization energy of the atom. In one experiment on potassium, the kinetic energy of the ejected electron was 5.34 x 10°J when the UV source had a wavelength of 162 nm. Calculate the ionization energy of potassium. %3D -19

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.
