What is one indicator that electrons in atoms are limited to specific energy levels?

There is a lot of evidence that backs this up, and is the reason that scientists needed to invent quantum physics to describe small molecules.
Atomic spectroscopy is probably the most convincing. When we shoot energy at atoms, only certain very specific energies are released. In addition, molecules will only interact with very certain specific energies of electromagnetic radiation. These tow things lead us to believe that electrons only have specific levels of energy.
In addition, there is a minimum energy that electrons can take, called the Zero Point Energy, below which electrons cannot go. It makes sense that there would be this minimum energy. Since electrons have a charge, they radiate energy as they orbit the charged nucleus of the atom. Eventually, the electron should radiate so much that it looses all its energy and fall into the nucleus. This would make matter very unstable. But because electrons only take on certain values, this doesn't happen!

How does the energy of core electrons compare with the energy of valence electrons?
The energy of the valence electrons is greater than the energy of the core electrons.
How does the energy of the core electrons compare with the energy of valence electrons?
The energy of the valence electrons is greater than the energy of the core electrons.
How does the energy of core electrons compare with energy of valence electrons?
The energy is higher.
In which direction does the electron rotate around the nucleus in an atom?
An electron doesn't have specific orbital path about an atomic nucleus. They move in specific energy levels that we identify as specific electron orbitals. But recall that the area where the electrons hang out is called the electron cloud. It's a "fuzzy zone" where electrons may be found. Electrons don't have specific routes about any atomic nucleus.
What are the energy levels of an atom occupied by?
that depends on the number of electrons the more electrons the more energy
One indicator that electrons in atoms are limited to specific energy levels is that?
light emitted from excited atoms occurs only at specific wavelengths
Who discovered that electrons move in specific levels or shells?
Neil Bohr discovered that each electron shell has specified energy levels and limited place for electrons.
A specific amount of energy related to the movement of electrons in atoms?
Energy level
What are the energy levels or energy shells and why is the outermost one important?
Energy level or energy shells are the specific locations where the electrons revolve around the nucleus. Each energy level is associated with specific amount of energy. The outermost is most important because it is the one which accepts the electrons from outside the atom or looses the electron.
Who was the scientist that said electrons are found in specific energy levels?
That was Niels Bohr
Did Neil Bohr propose that that electrons in an atom are found in specific energy levels?
yes
Why do electrons jump when heated?
electrons jump energy levels becouse each level has a specific amount of energy needed inorder to be in that level. when an electron gets enough energy it jumps to the next level it can possible be in with that amount of energy.
What do electrons do in Bohr's model of atoms?
In Bohr's atomic model, electrons are in specific orbitals (NOT orbits), which are at specific energy levels. An electron can go directly from one orbital to another, but it can never be in-between any two orbitals. The energy level of these orbitals is specified by angular momentum being quantized.
An indicator of the approximate energy of light?
Indicator of the amount of energy in a wave.
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.
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.
How does the energy of the core electrons compare with the energy of valence electrons?
The energy of the valence electrons is greater than the energy of the core electrons.
