When an electron in the ground state absorbs energy what happens?
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.
Some matirals are good counductors because they are able to easily transfer what patticals from one atom to another?
the conductivity of a material depends on the transfer of electrons from valence band to conduction band , when the two atoms come closer their outer energy shells (that are active in transfer of electrons ) get divided into two levels valence band which is full of electrons of lower energy and conduction band which is empty of higher energy. The gap between the two levels is called the forbidden energy gap which is a deciding factor for conductivity. for example in conductors these two bands overlap ,and in insulators there is a wide gap hence they are bad conductors ....

How electrons are jumping from one shell to other in the presence of forbidden zone of an atom?
may be electrons disappear from one shell when it receives it maximum energy and reappear at the other shell. or when the electrons receives it maximum energy it may convert into another form in band gap of an atom and again converted into its original form when it come it another shell which has fixed amount of energy...

What is forbidden energy?
The gap in energy that you are forbidden from visiting. It's a government conspiracy.
Do you find electrons in forbidden energy gap?
no
Is it possible to have an energy level in the forbidden gap?
Yes. In quantum mechanics, "forbidden" often means "unlikely" and not actually "no way, no how."
What is a difference between forbidden energy gap depletion region in semiconductor?
forbidden energy gap or energy gap or band gap or band or Eg is the gap between the top of the valance band and bottom of the conduction band. If we apply the energy equivalent to Eg then the electrons in valance band will jump to the conduction band. Ravinder kumar meena stpi n depletion region is the region in semiconductor where there is depletion of free charge carriers.Ravinder kumar meena stpi n
What is forbidden gap?
When atoms are brought close together, as in a solid, the electrons come under the influence of forces from other atoms, where the energy level merges into bands of energy levels. There are two distinct energy bands in which electrons could exist: the valence band and the conduction band . Separating these two bands is an energy gap , termed the forbidden gap, in which electrons cannot normally exist.Avinash SinghJr. YSR (ISCA)Mech. Eng.KIIT UnivesityBBSR

Titanium dioxide is direct band gap or indirect band gap material?
Yes it is. Most Sn (tin) materials as semiconductors are direct band gap materials. Silicon on the other hand is an indirect band gap material.
How you explain on atomic level that capacitor block dc?
Potential barriers. Insulators have a large band gap (forbidden gap) such that both electrons and holes have to possess enormous energy in order to have a chance to cross the barrier to the other side (DC blocking).
What does insulator mean in science term?
insulator is a material that can not go through the wire.for example rubber or plastic can not go through wire. insulator is a material in which the forbidden energy layer gap is more then 5 Mev
