The movements of particles within an atom cannot be frozen or stopped with liquid hydrogen or any other substance at ordinary temperatures and pressures. The behavior of particles within an atom, such as electrons orbiting the nucleus or nucleons within the nucleus, is governed by quantum mechanics and is inherently dynamic.
In the case of electrons, they occupy specific energy levels or orbitals around the nucleus. These energy levels are associated with specific quantized energies, and the electrons exhibit wave-like behavior. While it is possible to manipulate the energy states of electrons using techniques like cooling or trapping, it is not possible to completely freeze or stop their movements.
Regarding nucleons within the nucleus, the situation is different. The nucleons, which include protons and neutrons, are subject to the strong nuclear force that binds them together. Breaking or splitting the nucleus requires extremely high energies and specific conditions. This process is known as nuclear fission and typically involves bombarding the nucleus with highly energetic particles or inducing specific reactions.
Liquid hydrogen or any other common substance at normal temperatures and pressures cannot freeze the movements of particles within an atom or split the nucleus. These processes require specialized conditions and techniques that go beyond the capabilities of ordinary laboratory settings.
