Question

what is electronic configuration. explain with handmade diagram

Answer 1

Electronic configuration is arrangement of electrons in a specified manner around the nucleus to balance it. There are shells which can contain specified number of electrons only we call them as K, L, M, N
K shell contains - 2 electons
L shell contains - 8 electons
M shell contains - 18 electrons
N shell contains - 32 electrons
And so on...

For example:
Alumunium has 13 electrons hence its EC is
K - 2
L - 8
M - 3
