Cesium is often used in “electric eyes” for self-opening doors in an application of the photoelectric effect. The amount of energy required to ionize (remove an electron from) a cesium atom is 3.89 electron volts (1 eV = 1.60 x 10^-19J). Show by calculation whether a beam of yellow light with wavelength 5840 Å would ionize a cesium atom. Energy of the light beam = ______ eV Would a beam of yellow light with wavelength 5840 Å ionize a cesium atom?
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.
