The energy to ionize a certain element is 700 kJ/mol. What wavelength contains enough energy in a single photon to ionize one atom of this element?

Solutions

Expert Solution

1mol have 6.02x10²³particules so 700x10³J/mol x 1mol / 6.02x10²³particules = 1.16x10^-18J/particule

E = where h is planck = 6.62x10^-34Jxs and c is speed of light 3x10⁸m/s

= 6.62x10^-34J s x 3x10⁸m/s / 1.16x10^-18J = 171.20x10^-9m or 171.20nm

The ionization energy of a certain element is 352 kJ/mol. (Ionization energy is the minimum energy required to remove an electron from an atom. It is usually expressed in units of kJ/mol; that is, it is the energy in kilojoules required to remove one mole of electrons from one mole of atoms.) However, when the atoms of this element are in the first excited state, the ionization energy is only 166 kJ/mol. Based on this information, calculate the wavelength of...
