A
- 2
- 8
- 18
- 32
The number of electrons = 2n^2

A
A region within an atom that can hold up to 2 electrons, with opposite spins.
3
Q
What shape does an S orbital have?
A
A spherical shape
4

5
Q
What is the filling order of electrons?
A
1s2s2p3s3p4s3d4p4d4f
6
Q
What is the noble gas shorthand?
A
The noble gas shorthand uses the noble has from the period above the element that you are working the electron configuration out for. E.g the first 10 electrons are [Ne].
