Question

How many cells are used to write the electronic configuration of an element?

Answer 1

In atomic physics and quantum chemistry, the electron configuration is the distribution of electrons of an atom or molecule (or other physical structure) in atomic or molecular orbitals. ... This is also useful for describing the chemical bonds that hold atoms together.

Answer 2

There is no particular number of shells which is universal for the electronic configuration of every elements.

- The number of shells increases with the total number of the electrons present in a particular element.

- Also,a same element can get different number of shells due to negative and positive ions of that elements which changes the total number of electrons.

- That's why there is no particular number of shells for denoting the electronic configuration of an element.
