Starter 10/30 Draw the atomic model for Oxygen (O) If you can’t remember how to draw a Bohr diagram, write down all the information you know about oxygen based on the periodic table
Atomic Structure Sublevels
Draw the nucleus (label the p + & n 0 ) Draw the correct # of electron levels (# of electron levels = row #) Fill in the correct # of e - (# of e - in each level matches # of elements in each row) Bohr Diagrams
Bohr Model Practice Calcium Silver
Sublevels we can divide electron levels into regions called sublevels sublevelmaximum # of e - s2s2s2s2 p6p6p6p6 d10 f st energy level nd energy level 18 – 3 rd energy level 32 – 4 th energy level

Orbitals each sublevel is broken into orbitals each orbital can hold a maximum of 2 electrons orbital- a 3D region around the nucleus that has a high probability of holding electrons
