How the electrons are distributed in different orbits?please explain.
Answers
The number of electrons present in the orbits are calculated through 2n².
Explanation:
It is known that an atom consist of nucleus and electronic shells. In the nucleus of an atom neutrons and protons are present while electrons are revolve around the nucleus in orbits. These orbits are called energy levels. The 1st energy level closer to the nucleus is called K shell. The second is called L shell and so on.
The electrons present in orbits closer to the nucleus are stable and having lower energy while the orbits away from the nucleus are at higher energy and are unstable.
The number of electrons present in these orbits are calculated through 2n².
Here n is the energy level.
For example for 1st energy level or K shell the number of electrons are
2(1)² = 2 (1s²) s and p are subshells
For L shell,
2(2)² = 8 (2s² 2p⁶)
Answer:
I hope my answer helps you
Explanation:
The distribution of electrons into different orbits off atom was suggested by Bohr and Bury.
The following rules are followed for writing the number of electrons in different energy levels or cells.
(i) the maximum number of electrons present in a cell is given by the formula 2n², where "n" is the orbit number for energy level index, 1,2,3.....
Hence the maximum number of electrons in different cell are as follows:
first orbit or K-shall will be=2×1²=2
second orbit or L-shall will be=2×2²=8
third orbit or L-shall will be=2×3²=18
fourth orbit or N-shall will be=2×4²=32
(ii) the maximum number of electrons that can be accommodated in the outermost orbit is 8
(iii) electrons are not accommodated in a given cell,unless the inner shell are filled.That is, the shells are filled in a step-wise manner.
