Question #1: The electronic energy is the sum of the following:
(1) The coulombic interaction of all of the electrons in the molecule with all of the nuclei in the molecule. (All of these attractive forces and negative energies.)
(2)The coulombic interaction of all the electrons in the molecule with each other. (All of these are repulsive forces and positive energies.)
(3)The coulombic interaction of all of the nuclei in the molecule with each other. (All of these are repulsive forces and positive energies).
(4)The magnetic interaction of all the particles (electrons and nuclei) in the molecule.
(5)The kinetic energy of all the electrons.
Question #2: What or whose law mathematically describes the potential energy of interaction between a positively charged particle and a negatively charged particle?
Question #3: Use the law from Question #2 to show that the potential energy of interaction between a positive and a negative charge is a negative quantity.
Explanation / Answer
#1) - 2 #2) coloumbs law of attraction #3)U= - Kq1 *q2 *(1/r) (acc coloumbs law for potential energy interaction) now taking q1 = +e taking q2 = -e and substituting in the equation U= - e^2 *k/r hence its a negative quantity.
