Question

Introduction to electronic configuration class 9 in 2 to 3 paragraphs

Answer 1

Answer:

The electron configuration of an element describes how electrons are distributed in its atomic orbitals. Electron configurations of atoms follow a standard notation in which all electron-containing atomic subshells (with the number of electrons they hold written in superscript) are placed in a sequence

Answer 2

The electronic configuration is the number of atoms in shells. For example, KLM shells in 2,8,2
Remember that the second she’ll can only hold 8 number of electrons

Argon- Atomic number - 18
So, K=2

L=8

M=8
