Ionic (electrovalent)bond |
Occurs when elements on the left electro positive metals meet those on the right electronegative nonmetallic if electronegative difference on the Pauling scale is greater than 1.7 this will form
Face centered cubic |
|
|
Covalent bond |
Sharing of electrons formed when both atoms are on the right (electro negative nonmetals) and has a small difference in electronegativities Unequal sharing |
|
|
Ionic bond |
C |
|
|
Metal bonds to nometals |
Forms ionic salt Metals conduct electricity High melting point |
|
|
Electrostatic attraction |
Example NaCl Na atom Losses of an electron (+) Cl gains the electron (-) |
|
|
Water and ionic compounds |
Water breaks bonds and electrolyte are free and can now conduct electricity. |
