For the metal iron (Fe), with parameters as follows, plot the Lennard Jones potential in DESMOS and obtain: The average distance between the atoms when the energy is minimum (the x-axis is in Angstrom, where 1 A = 1*10-10m). Answer TO The energy needed to break the bond (the y-axis is in electron volts, where leV = 1.60218*10-19J). Answer eV The average distance between the atoms if the total energy (the one above the minimum) were half the energy needed to break the bond. (You can estimate that this distance falls in the middle between the two extremes of the vibration movement with that amount of energy.) Answer The wavelength of a photon with enough energy to break the bond (NOTE: this is MORE than just moving to the next vibrational energy level). The energy of a photon is E hc/1 where his Plank's constant, c is the speed of light in vacuum, and I is the wavelength of the color of light to which that photon corresponds. Inm=1* 10-9m Answer nm Identify whether the photon is from a radio wave, microwave, infrared light, visible light, ultraviolet light, X-rays, or gamma rays.
