a.)Does 1 atom have rotational modes?
b.)What is the MAX number of modes that one atom can have?
c.)Can a diatomic molecule have vibrational modes?if so, how many? For each vibrational mode what types of energies are present?
d.)Categorize the modes into types of kinetic and potential energy modes
a) No, a single atom can't have rotational model. As the moment of inertia will be very small, So rotational effect will be negligible.
b) One atom can have a maximum of 3 translational modes.
c) Yes a diatomic molecule can have vibrational modes at very high temperatures. A diatomic molecular can have one vibrational degree of freedom. Each mode carry on an average (1/2) k T of energy in the form of vibration.
d) Each translational and rotational mode corresponds to kinetic energy modes. And each vibration mode correspond to potential energy mode.
