2 Electron Arrangement What do we know? e- are in the e- cloud

3 Electron Arrangement What do we know? e- are in the e- cloud e- are responsible for the volume of the atom

4 Bohr Model

5 e- move certain distances from the nucleus

6 Bohr Model e- move certain distances from the nucleus – close to nucleus have less E – E increases as e- move away from nucleus

7 e- move with certain speeds due to E

8 – give off E only when they move to a lower E level

9 e- move with certain speeds due to E – give off E only when they move to a lower E level outer most e- are called valence e- and have the most E

10 e- move with certain speeds due to E – give off E only when they move to a lower E level outer most e- are called valence e- and have the most E – valence e- determine behavior of atoms and are involved in bonding
