According to the Bohr model of hydrogen atom, the kinetic and potential energies of the electrons vary as .......... ..and... distance of electron from the nucleus. respectively. where r is the The square of the wavefunction, y}, gives us the Absorption of a given amount of energy gives rise to a larger increase in entropy the the initial temperature. Orbital energies in multi-electron atoms are mere difﬁcult to calculate due to the additional Select the correct answers from the following multiple choice questions. Each .y...~4o‘m: correct answer carries 1.0 mark and for each wrong answer 0.25 marks will be deducted.
