An energy level refers to a confined particle such as an atom, the energy level refers to how excited the electron is ie if an electron in the ground state (level 0) receives the correct amount of energy it will move to level 1.
Energy band refers to something much more complex, it is more commonly known as band structure and describes all the energy levels that a particle such as an electron is allowed to be in and those which it is not.
Basically, energy level is for a single confined particle, energy band is for when lots and lots of electrons come together for instance in a crystal structure

What is the difference between the band structure of a semiconductor and that of a metal?
In a semiconductor, the band structure has a small energy gap between the valence and conduction bands, allowing for some electrons to move from the valence band to the conduction band when excited. In a metal, there is no energy gap between the bands, allowing electrons to move freely throughout the material.
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.

What is the difference between the valence band and the conduction band in a material's electronic structure?
The valence band is the energy band in a material where electrons are normally found, while the conduction band is the energy band where electrons can move freely to conduct electricity. The key difference is that electrons in the valence band are tightly bound to atoms, while electrons in the conduction band are free to move and carry electric current.
When stretching a rubber band between your fingers gives it kinetic energy?
No. The rubber band stores energy as elastic potential energy. U = (1/2)*k*(L)^2 where, U is the stored energy k is the spring constant for the rubber band L is the displacement
What is the value of band gap of zinc selenide?
The band gap of zinc selenide is approximately 2.7 electron volts (eV). This value indicates the energy difference between the valence band and the conduction band in the material. Zinc selenide is a semiconductor commonly used in optoelectronic applications due to its wide band gap.
What is the difference between electronic band and subband in solid state physics?
When energy is quantized, each of the levels corresponds to one band. But each level can depend upon the total velocity or position. If one energy level depends on each of coordinates, each coordinate can give a contribution to the total energy. This represents a subband.
What is the difference between direct and indirect energy?
The band gap represents the minimum energy difference between the top of the valence band and the bottom of the conduction band, However, the top of the valence band and the bottom of the conduction band are not generally at the same value of the electron momentum. In a direct band gap semiconductor, the top of the valence band and the bottom of the conduction band occur at the same value of momentum.In an indirect band gap semiconductor, the maximum energy of the valence band occurs at a different value of momentum to the minimum in the conduction band energy
What are the difference between direct and indirect band gap materials?
In a direct band gap the electron only needs energy to jump to the conduction band. In an indirect band an electron needs energy and momentum to jump to the conduction band
Why acceptor energy level is near to valence band in p-type semiconductor?
valance band has lower energy level

What is the difference between chain printer and band printer?
The difference between a chain printer and a band printer is a chain printer has a chain that the characters are on and a band printer has a band for the characters.
What is energy gap?
there will be only certain energy levels in which electrons get filled up. In valence orbitals there will be many such energy levels and the energy gap between conduction band and valence band is called energy band gap.
What is the difference between gastric band and lap band surgery?
The difference between gastric band surgery and lap band surgery is the type of procedure which is undertaken and the complications which may arise from the surgery.
What is the difference between a band with a guitar and a band without a guitar?

What is valence band?
It is the band of energy of an electron in outer most orbit
