Question

explain the borh burry scheme for felling electron in shell​

Answer 1

according to Bohr model ,in an atom electrons are arranged in various shells around the nucleus and they are filled in the increasing order of energy.

• As the distance from the nucleus increases, the energy of the electrons in the shells increases

and the attractive force between the nucleus

and electrons decreases.

Explanation:

1. Electrons move around the nucleus in specified circular paths called orbits or shells or energy levels.
2. Each orbit or shell is associated with a definite amount of energy .Hence ,these are also called energy levels as designated as K,L,M,N shells.
3. The energy associated with a certain energy level increases with the increase in its distance from nucleus. Hence, if the energies associated the K,L,M and N shells are E1,E2,E3,and E4 , respectively E1<E2<E3<E4......,and so on.
4. As long as the electron revolves in a particular orbit , the electron does not lose its energy . Therefore ,these orbits are called stationary orbits and the electrons are said to be in stationary energy states.
5. An electron jumps from a lower to a higher energy level by absorbing energy .It jumps from a higher to a lower energy in the form of electromagnetic radiation. The energy emitted or absorbed (∆E) is given by plank's equation ∆E=hv. for example ,if E1 and E2 are the energies of first and second orbits , respectively , then the difference in energy is equal to hv:E1-E2=hv.

• An electron can revolve only in an orbit which the angular momentum of the electron (mvr) is a whole -number multiple of h/2π. This is known as the "principle of quantanization of angular momentum". Hence we can conclude the angular momentum aof an electron as mvr=nh/2π,where n=integer (n=1,2,3,4.....) and is called principal quantum number . m=mass of the electron ,v=velocity of an electron in its orbit ,r=distance of electron from the nucleus (radius)by applying the concept of quantanization of energy , Bohr calculated the radius and energy of the nth orbit of hydrogen (Z=1). ******************************************************** **(NB: please mark as brainliest )
