The <span>modern-day quantum model of the atom known as the wave mechanical model depicts that the </span>electron was a three dimensional wave circling the nucleus in a whole number of
wavelengths allowing the waveform to repeat itself as a stable standing wave
(it can absorb energy form a nearby source which is oscillating at a proper
frequency) representing the energy levels of Bohr model.

Answer:
Melting = endothermic, solid = exothermic
Explanation:
Ok so when ice cream melts, that requires heat, so it’s Endothermic. In order to melt it, it requires heat, heat is entering. When it becomes solid again, that is exothermic because it is losing heat in order to become cool again.
