[object Object],Bohr Diagrams Carbon Atomic # = 6 Mass # = 12 Atomic mass = 12.011 amu

[object Object],Bohr Diagrams ,[object Object],[object Object],[object Object],[object Object],Carbon Atomic # = 6 Mass # = 12 Atomic mass = 12.011 amu C 6p + 6n 0

[object Object],Bohr Diagrams Carbon Atomic # = 6 Mass # = 12 Atomic mass = 12.011 amu ,[object Object],[object Object],Carbon is in Period two and therefore needs two energy levels C 6p + 6n 0

[object Object],Bohr Diagrams Carbon Atomic # = 6 Mass # = 12 Atomic mass = 12.011 amu The number of electrons should be equal to the number of protons. Remember: C 6p + 6n 0 If you need a third level make your circles a little smaller. 8 3 8 2 2 1 # of e - Energy Level

Electron Dot Diagrams ,[object Object],C

Electron Dot Diagrams ,[object Object],C Carbon has only 4 electrons in the 2 nd energy level so we need only represent those 4 Like the Hund rule add 1 electron per side, then add more as needed.

Electron Dot Diagrams ,[object Object],C Only s and p sublevel electrons in the outer or highest energy level are shown. These are called valence electrons. The maximum number of electrons that can be shown are 8

Electron Dot Diagrams ,[object Object],O The maximum number of electrons that can be shown are 8 Only s and p sublevel electrons in the outer or highest energy level are shown. These are called valence electrons.

Electron Dot Diagrams ,[object Object],Cl The maximum number of electrons that can be shown are 8 Only s and p sublevel electrons in the outer or highest energy level are shown. These are called valence electrons.

Electron Dot Diagrams ,[object Object],Li The maximum number of electrons that can be shown are 8 Only s and p sublevel electrons in the outer or highest energy level are shown. These are called valence electrons.
