Question

explain orbit and distribution of electrons iin shells​

Answer 1

Answer:

orbits/ shells are the circular around the nucleus of an atom along which the election transevrese.

Answer 2

The arrangement and distribution of electrons in different orbits was given by Bohr and Bury. The arrangement of electrons in different shells and sub-shells is known as the electronic configuration of a particular element. The electronic configuration diagram represents an element in its ground state or stable state. There are a set of rules to remember while distribution off electrons in different orbits

Rule 1:

The maximum number of electrons present in a particular shell is calculated by the formula 2n2, where “n” represents the shell number. For instance, K shell is the first shell and it can hold up to 2(1)2 = 2 electrons. Similarly, L shell is the second shell and it can hold up to 2(2)2 = 8 electrons. This formula helps to calculate the maximum number of electrons that an orbit can accommodate.

Rule 2:

The maximum capacity to hold electrons in the outermost shell is 8.

Rule 3:

The electrons will fill the inner shells before the outer shells. First electrons will fill the K-shell and then L shell and so on. Thus, electronic configuration of elements follows an ascending order.
