2m1Li,2m1HLiH2mLi1Li,2mH1H Are these terms positive or negative when used in the Hamiltonian operator? positive | negative Step 2 of 7 Assuming that the subscript "1" represents the electron on the hydrogen atom and the subscripts "2", "3", and "4" represent the electrons on the lithium atom, list the terms that represent the kinetic energies of the electrons. (Enter your answers as a comma-separated list. Use to represent the Laplace operator, 2. Use the following as necessary: 1,2,3, and 4.) Are these terms positive or negative when used in the Hamiltonian operator? positive negative
