1
Q
What space do electrons occupy?
A
Electron shells (sometimes called energy levels).
2
Q
How many electrons are in the 1st, 2nd and 3rd shells?
A
1st shell: 2
2nd shell: 8
3rd shell: 8
3
Q
How do you work out the electronic configuration?
A
Follow the Electrons Shell Rules, so the first shell can only take a maximum of 2 electrons, and 2nd and 3rd can only take 8.
