Thomson also experimented with shining ultraviolet light at metal electrodes, such as zinc, to produce cathode rays (i.e., beams of electrons). The minimum energy required to eject one electron from zinc is 6.94 × 10-19 J. a) Based on the information above, what is the maximum wavelength of light that can be used to eject an electron from zinc (Zn)? Clearly show what equation(s) and values you used to calculate this energy. b) In the space below, draw a graph of kinetic energy of ejected electrons (J) vs. photon energy (J). Label your axes and the threshold energy. c) Explain how your graph appropriately represents the relationship between electron KE, photon energy, and threshold energy as demonstrated by the photoelectric effect.
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.
