Electronic Structure
Key Stage 4
Meaning
The electronic configuration of an atom is the way the electrons are arranged in orbitals around the nucleus.
About The Electronic Configuration
- The electronic configuration of an atom is written by stating the number of electrons in each electron shell.
- As an example Argon has 2 electrons in the first shell, 8 in the second and 8 in the last, so the electronic configuration is 2,8,8.
