it's hard to draw arrows on this, so a \ will be an arrow going one way and a / will be the other way. a [ ] represents a box.

the bohr Rutherford diagram for aluminum is... two dots on the inner level then 8 dots on the second level then 3 dots on the outer level.
The electron configuration of aluiminium is: [Ne]3s23p1.
An orbital diagram is used to show how the orbitals of a subshell areoccupied by electrons. The two spin projections are given by arrowspointing up (ms =+1/2) and down (ms = -1/2). Thus, electronicconfiguration 1s22s22p1 corresponds to the orbital diagram:

The electron configuration of helium is 1s2.
24 Cr3d5 4s1
1s2, 2s2 2p2
Boron has:- 1s2 2s2 2p1
An orbital diagram is used to show how the orbitals of a subshell areoccupied by electrons. The two spin projections are given by arrowspointing up (ms =+1/2) and down (ms = -1/2). Thus, electronicconfiguration 1s22s22p1 corresponds to the orbital diagram:

The arrows indicate the spin of the electron, which is either +1/2 or -1/2. This it also indicates the magnetic quantum number, or the fourth quantum number.
