  2. Electron Arrangement(Energy Levels, Sublevels, Orbitals) • Electrons travel around the nucleus at certain distances, called energy levels. • Inside each energy level, there are sublevels; the number of sublevels is equal the number of the energy level: • 1st energy level has 1 sublevel (s) • 2nd energy level has 2 sublevels (s, p) • 3rd energy level has 3 sublevels (s, p, d) • 4th energy level has 4 sublevels (s, p, d, f) • 5th energy level has 5 sublevels (s, p, d, f, g)

  3. Electron Arrangement (cont.) • Inside each sublevel, there are orbitals –specific regions/areas inside the e cloud where individual e’s exist. • An orbital may be empty, or may hold 1 or 2 e’s. Any orbital can hold a maximum of 2 e’s. • An outer level (valence level) can hold a maximum of 8 e’s. So, an outer level has a maximum of 4 orbitals.

  4. Electron Arrangement (cont.) • Stated another way, an outer level has a maximum of 2 sublevels (s, p). • An s sublevel has 1 orbital; a p sublevel has 3 orbitals. Total = 4 orbitals = 8 e’s (2 per orbital). • Valence electrons exist in these outer 4 orbitals.
