What were the four principles of the bohr model?
The four principles of the Bohr model are: electrons orbit the nucleus in fixed energy levels or shells, electrons can jump between different energy levels by either absorbing or emitting photons, angular momentum of electrons is quantized, and the frequency of emitted or absorbed light is directly related to the energy difference between electron levels.
Why do cations emit colors when heated in a Bunsen burner flame?
Transitions between electronic energy levels release electromagnetic radiation corresponding to the energy difference between the levels. The heat promotes the electrons to the higher level; when they drop back down to the lower level a specific color of light is emitted.
Is there any other energy state aside from the lowest energy state for an electron?
Yes, while nature will always try to place electrons in their lowest energy configuration, electrons can temporarily occupy higher energy states. When they fall back to the lowest energy state, the difference in energy is released as light - "a photon". Different colors of light reflect differing energy state jumps made by electrons.
Do neutrons have more energy than electrons?
No, Neutrons are nuetral so they do not move in different energy levels. Only Electrons do.
Do atoms absorb the same energy?
No, atoms do not absorb the same energy. The amount of energy an atom can absorb depends on its electronic structure and the specific energy levels of its electrons. Different atoms have different numbers of electrons and different energy level arrangements, so they will absorb and emit energy at different wavelengths and energies.
Electrons can only absorb photons that have energy equal to what?
Electrons can only absorb photons that have energy equal to the energy difference between two allowed energy levels in the atom or molecule.
What were the four principles of the bohr model?

Do electrons have different amounts of energy?
Yes, electrons can have different amounts of energy. In quantum mechanical systems where any particle (not just electrons) are bound, they can only acquire discrete amounts of energy called energy levels. Adding energy to an electron in an atom might cause it to jump to a higher energy level and is then said to be in an excited state; if it were to fall to a lower level it would give up a discrete amount of energy equal to the difference in energy between the two states.

What is difference between electrical and electricity?
Electrical is an one type of energy ie flow of electrons... this flow of electrons constitutes the Electricity which we are using for our use
Why do elements have a characteristic color when exposed to heat?
u can give your daughter or son one cent but can u give half cent? similarly things in nature are quantized - they can release energy only equal to difference of the energy level their electrons can jump so, as arrngement of electrons is different in different elements so is the difference in frequencies they emit hence the different colours
Why do electrons emit light when they fall down to their ground state?
When electrons fall down to their ground state, they release energy in the form of photons of light. This is because the energy difference between the higher energy state the electron was in and the ground state is emitted as light. The wavelength of the light emitted depends on the specific energy difference between the two states.
When excited electrons radiate energy the amount of energy given off is equal to?
The amount of energy given off by excited electrons when they radiate energy is equal to the difference in energy level between the initial and final states. This emitted energy is typically in the form of photons.
What is the difference between the homo and lumo energy levels in molecular orbital theory?
In molecular orbital theory, the HOMO (highest occupied molecular orbital) is the highest energy level that contains electrons, while the LUMO (lowest unoccupied molecular orbital) is the lowest energy level that does not contain electrons. The difference between the HOMO and LUMO energy levels determines the reactivity and stability of a molecule.
What is the different between endothermic and endothermic?
The difference between endothermic and exothermic energy is that exothermic energy is the reaction that releases energy and endothermic is the reaction in ehich energy is absorbed.
What is the Measure of the energy available to move electrons or potential difference?
potential energy
What is the difference between a neutral atom an ion and an excited atom?
A neutral atom is an atom with an equal number of electrons and protons without any additional energy. An excited atom has electrons that have absorbed energy and moved up to another layer. Ions are atoms that have a different number of electrons from the neutral atom.
