Question

what are the symbols used for the shells which accommodate the electrons in various atoms ??​

Answer 1

Answer

All the shells are represented by letters called K, L, M, N shells. These shells accommodate different number of valence electrons depending on the chemical properties of that element.

Answer 2

Answer:

All the shells are represented by letters called K, L, M, N shells.

These shells accommodate different number of valence electrons depending on the chemical properties of that element.

Explanation:

Hydrogen has atomic number 1. So the valence electrons in the shells are represented as : K -1

Sodium has atomic number 11. So it will be represented as K-2, L-8, M - 1

So all the shells are represented with different alphabets. Also the number of electrons that can be accommodated in a shell can be given by the formula 2n², where n represents the number of shells.
