do all of the electrons in an atom have to move up or down an energy level or is it just the valence electrons or what? is there one photon released per electron and are they all the same wavelength?
kashiark said:but if only one electron did this and changed energy levels wouldn't it change the chemical properties of the atom? for instance, if one electron in helium moved up an energy level it wouldn't be stable anymore and it would have different chemical properties
kashiark said:ah i see ok ty and i meant chemically stable but i have another question; if you rub two objects together underwater they can keep putting out heat energy forever; once all of the electrons are in their lowest level wouldn't the heat energy stop being put out? or does the kinetic energy from moving the objects cause some of the electrons to move up an energy level?
Quantum mechanics is a branch of physics that studies the behavior and interactions of particles at the subatomic level. It provides a mathematical framework for understanding the fundamental properties of matter and energy.
The Bohr model of the atom was proposed in 1913 and is based on classical physics principles. It describes electrons orbiting around a nucleus in specific energy levels. In contrast, quantum mechanics takes into account the wave-like nature of particles and describes the behavior of electrons in terms of probabilities and wave functions rather than fixed orbits.
The Bohr model was successful in explaining some properties of atoms, but it failed to explain the complex behavior of electrons in more complex atoms. It also did not account for the dual nature of particles as both waves and particles. Quantum mechanics provides a more comprehensive and accurate understanding of the behavior of particles at the atomic level.
Quantum mechanics has revolutionized our understanding of the physical world by providing a more accurate and comprehensive description of the behavior of particles at the subatomic level. It has led to advancements in technology, such as transistors and lasers, and has also allowed for the development of new fields of study, such as quantum computing and quantum information theory.
While quantum mechanics has largely replaced the Bohr model in terms of accurately describing the behavior of particles, the Bohr model is still used as a simplified model in some contexts, such as introductory physics courses. However, quantum mechanics provides a more complete and accurate understanding of the physical world and is considered the foundation of modern physics.
