  1. Covalent Bond Video

  2. A covalent bond is the chemical bond formed between two 
atoms when they share electrons in pairs. When atoms come 
near each other, their electrons are attracted towards the 
nucleus of the other atom. If the outside shell is not filled, this 
attraction becomes stonger. The electrons are now being shared by both atoms, and 
they both have a full outer shell.

  3. Covalent bonds - a bond formed when atoms share 
electrons to obtain full outer energy levels energy levels are at least half full of ve- all non metals

  4. Solutions do not conduct electricity Low melting points - less than 300 Low boiling points Some have a strong odor Weak Bonds

that are covalently bonded. Use the highlighter to select the compounds 
that are covalently bonded. H2O HCl NaF CO2 LiO MgO NaCl CH4 NH3

  6. E-Dot Diagrams Examples: H Cl Br Br

  7. Double covalent bonds - share two pairs of electrons

  8. Triple covalent bonds - share 
three pairs of electrons Triple bonds are harder to break than 
double bonds - takes more energy. Double 
and triple bonds are shorter than single 
bonds

  9. Binary Covalent Compounds end in ide. BF3 When there is only one first 
element ,do not use Mono prefix Boron trifluoride N-nitr ide P-phosphide S-sulfide Cl-Chloride F-fluoride O-oxide I-iodide Br-bromide 4.3.6

  10. Polar Covalent Bonds - electrons 
are attracted to the nucleus of 
one atom more than another Example: H20   

  11. Nonpolar Covalent Bond 
- electrons are shared 
equally between the 
nucleus of atoms as they 
have equal attraction Example: H2

  12. Electronegativity H-F Example
