Atomic Theory

name all the sublevels

s, p, d, f (remember spdf is vds)

how many e^- does the s sublevel have and how many orbitals?

2 electrons, 1 orbital

how many e^- does the p sublevel have and how many orbitals?

6 electrons, 3 orbitals

how many e^- does the d sublevel have and how many orbitals?

10 electrons, 5 orbitals

how many e^- does the f sublevel have and how many orbitals?

14 electrons, 7 orbitals

what is this?

aufbau’s principle pattern (helps determine the electron configuration)

4 atomic structures

electron config., orbital box diagram, energy level diagram, and bohr

Exceptions to the filling order

• For d-block (transition metal) cations remove the outermost electrons in the s-orbital first, before removing any d-orbital electrons

• Transition metals (d-block) that have 4, 8, or 9 electrons will STEAL electrons from the nearest s-orbital

Note: extra stability comes with a filled or half-filled sublevel
