The electrons have a set amount of energy, arranged into levels of increasing energy the farther they are from the nucleus. So, for example, E=1 is the first energy level where the energy of the electron is what that energy level is too.
Also, as you go out, the energy levels get closer together. So, E3 and E2 are closer together than E1 and E2.
Basically, electrons cannot have an energy lower than the first energy level. It would have to be lower for the electron to get to the nucleus. But it cannot go that low. Bohr discovered that it happened, and I think we're still looking for why it doesn't

What did Niels Bohr discover?
Based on conversations with Rutherford Niels Bohr developed the Bohr-Rutherford nuclear model of the Atom. It is the one you have met in elementary school where Protons and Neutrons form a core with electrons circling in fixed orbits around the core. The orbits explained (some kind of) radiation which had hitherto been a mystery. He discovered that electrons in atoms are arranged according to the energy levels.
What was Niels Bohr's key hypothesis about the behavior of electrons in atoms that he formulated to explain the discrete pattern of atomic spectra?
That electrons can orbit their nucleus in only certain discrete orbits at certain specific levels of energy
Sharing of electrons in the outer energy levels of two atoms?
The sharing of electrons in the outer energy levels of two atoms is called bonding.
How many energy levels are in an atoms of Mg?
3
How did Niels Bohr discover the atomic structure?
The atom had been theorized for ages before an experiment was done by Rutherford and his student to prove that gold was composed of atoms. They bombarded gold foil with alpha particles (He nuclei), and the particles occasionally deflected by a large angle, but would normally pass straight through. This proved there were atoms with tiny nuclei composing gold.
Did Niels Bohr invent atoms?
No one invented atoms, atoms were discovered. Niels Bohr did not discover or invent the atom, he did however create a model of the atom.

Can atoms change energy levels?
no, electrons can
What is found in the energy levels of atoms?
electrons

Who developed the idea of electron shell?
Niels BohrNiels Bohr proposed the first model of the atom with distinct energy levels with quantized energies. He proposed this theory based on the spectra of atoms and ions.

What atoms have two outer level electron?
Energy levels
How are atoms and energy related?
Vibration is related to energy. Or on a more complex level, atoms posses electrons, which in the bohr model, are at different energy "levels"
Why does sodium have electrons that are not arranged in its energy levels?
Sodium atoms do have electrons that are arranged in energy levels. The electron configuration of sodium is 1s22s22p63s1.
What the is energy levels in an atom?
1. Atoms do not have energy levels unlike particles like electrons etc.2. The lowest energy for atoms will be 0 at absolute zero temp of 0 deg Kelvin.3. For electrons in all atoms lowest energy is that of 2 electrons nearest to the nucleus.
