Explain Bohr Bury Scheme for the distribution of electrons.
Answers
The distribution of electrons in different orbits or shells is governed by a scheme known as Bohr bury scheme. The arrangement of electrons in various energy levels of an atom is known as the electronic configuration of the atom. According to this scheme. ... The third shell can accommodate as many as 18 electrons.
Answer:
According to Bohr’s model, electrons occupy certain stable orbits or shells. Each shell has definite energy.
These orbits or shells are represented by the letters K, L, M, N, … or the numbers 1, 2, 3, 4, …
The maximum number of electrons present in the shell is given by the formula (2 n2), where n is the orbit number or shell number.
The maximum numbers of electrons in different shells are as follows:
The first orbit or K shell will have 2 × 12 = 2 electrons.
The second shell will have 2 × 22 = 8 electrons.
The third shell will have 2 × 32 = 18 electrons.
The fourth shell will have 2 × 42 = 32 electrons and so on.
The maximum number of electrons that can be accommodated in the outermost orbit is 8.
The orbits or shells are filled in a step-wise manner.
Electrons are not accommodated in a given shell unless the inner shells are filled
