[@rumman8708]

If anyone is wondering the reason for splitting, It is a very complex theory based upon molecular orbital theory which explains that elements having unpaired electrons are good conductors. Splitting of bands is actually the involvement of orbitals of different atoms of the elemental crystal. This is the simplest way in which I can explain the reason.

Outstanding sir👍 sir I have a question why there is difference between the forbiden gap of insulator , conductor and semiconductor? It depend on their nature🤔

[@physicskasafar]

Because electrons are tightly bounded in insulators And free electron in conductors That is why their energy gaps are different

Sir why atoms tend to go in Lower energy orbits Or say lower energy band rather than Higher... Please Answer Karden

Every thing wants to be in lowest energy state nearest to the nucleus.ashiq hey electron apne barbadee par tula hota he nucleus ke andhar ie ghar ke andhar protons ke leay.opree hessa khali reh jata hey.donon parts main separation energy gap he.os space main slectron nahee reh sakta.

[@Physicsfun812]

Energy band theory is not fully describe ......reasons of bands and energy gap ?????????

[@physicskasafar]

When an energy level splits in to many energy levels in a crystal then it is look like a band. When these energy levels splits into low and high energy band then valence and conduction band are formed. And the gap between these energy levels or valence band and conduction band is called forbidden energy gap

[@Physicsfun812]

But why gap formed ??? And why energy bands formed ??? Give reasons

[@physicskasafar]

Daikhain jb hm Aik energy level k baat karte hain to uss main sb electrons ki energy same hoti hain. Yani isolated atom main Lekin jb hm crystal ki baat karte hain to uss main lakhon caroron atom hote hain to electrons ka interaction Baki atoms k nucleus aur baki atoms k electrons k Sath b hota ha jis ki wajeh se hr electron ki energy different ho jati ha aur boht se energy levels bn jate hain. Jo hamain Aik band ki tarhan Nazar aate Hain. Iss liye hm uss ko energy band kehte hain. Ab in main kuch low energy level hoon ge kuch high energy level to unn ki splitting ho jati ha. Khud bakhud To iss ki wajeh se jo lower energy aur higher energy states k darmayan gap bn Jata h uss ko hm kehte hain forbidden energy gap

[@physicskasafar]

Ager ab b samajh Ni aaai to video ko ghor se daikhain uss main ye sb batain samjhai hui hain
