1. Covalent Bonding

2.  Atoms share electrons  Occurs between two non-metals

3. Non-Polar Covalent  Atoms share electrons equally

4. Polar Covalent  Atoms share electrons unequally

5. Electronegativity (Electron Greed)  Used to measure how much an element wants an electron  The higher the EN, the more it wants an e-  Difference in EN between atoms will predict the type of bond

6. E.N. Difference Type of Bond E.N. Difference Character Nonpolar Covalent 0 Sharing e - completely Polar Covalent 0 – 1.7 Unequal sharing of e - Ionic Greater than 1.7 e - transferred

7. Covalent Compound Prefixes  mon(o) – 1  di – 2  tri – 3  tetra – 4  penta – 5  hexa – 6  hepta – 7  octa – 8  nona – 9  deca - 10 Prefixes trianglePentagonoctopus

8. Naming Covalent Compounds  Name each element  Add prefixes to show how many atoms  End the last element in “ide”  The prefix “mon” is not used for the first element listed

9. Examples P2O5 =P2O5 =P2O5 =P2O5 = phosphorusoxygendipent -ide CCl 4 = carbon carbon chlorine chlorinemontetra -ide PCl 3 = phosphorus trichloride dinitrogen monoxide N 2 O =

10. Diatomic Molecules  H 2  I 2  Br 2  O 2  N 2  Cl 2  F 2 HI BrONClF
