Explanation Introduction: The electron can be move from lower energy state to higher energy state by giving them some external energy. The external energy is gained by absorption of photons of required energy. This process of moving the electron to higher energy state is known as excitation of electrons. The electrons transit from lower energy state to higher energy state by absorbing energy in the form of photons. The materials emit various wavelengths of light which relates with the energy levels. In excitation process, the electrons excite from ground to higher state by absorption of photons in this florescence the electron the material. These excited atoms can be de-excited by several ways such as transition of electron to ground state by re-emits the same energy photons. This process is known as de-excitation. The fluorescence is a process in which excitation of molecules and atoms of given energy photon and de-excites by emission of a lower-energy photon. In de-excitation process if the photons emits in smaller steps by emitting energy of different from that excited it. Conclusion: Here, the electron excited from energy level 1 to energy level 8 . For the fluorescence effect by the electron it should be de-exited in smaller steps with lower energy from that excited it

The Bohr model

Students often get confused between Rutherford’s model and Bohr model of an atom. They interpret the postulates of both these models to be the same, which is incorrect. Rutherford’s model differs from Bohr’s model in the following ways:
