By definition, no object can go to a lower energy level than its ground state. Bohr simply assumed that the ground state of an electron in an atom was due to the minimum amount of angular momentum it could have. An electron could have that minimum amount (we'll call it 'h') or two times h, or three times h; but never less than h, and never a fraction of h.
Since an electron can never go to a lower energy level than its ground state, it can't give up energy.
When an electron returns to its ground state it emits energy in the form of light.
When an electron moves to a lower energy level, the difference in energy appears in the form of a photon, which the electron emits.
Because they absorb energy.
jumps to the a higher orbital. This is only possible if the energy it absorbed is large enough to let it jump the gap. If the energy is not large enough for the electron to jump that gap, the electron is forbidden to absorb any of that energy.
2nd energy level, the electron arrangement is 2,1 at ground state
An excited electron releases a photon as it returns to ground state.
When an electron returns to its ground state it emits energy in the form of light.
Ground state.
An electron possesses more energy in the excited state than the ground state.
The inner, or K shell, of the electron cloud has the least energy.
This electron is in an excited unstable state.
If there is an extra electron in the valence level then the electron is in the excited state and is carrying more energy. If the atom is normal then it is in the ground stte and contains low energy.
When an electron moves to a lower energy level, the difference in energy appears in the form of a photon, which the electron emits.
the lowest energy level occupied by an electron when an atom is in its most stable energy state
When the atom absorbs energy of the proper frequency/energy.
yes
Because they absorb energy.
