Name the three types of chemical bonds |
ionic bonds covalent bonds hydrogen bonds |
|
|
Ionic bonds |
-This bond occurs between ions -the number of protons doesn't equal the number of electrons -the transfer of valence shell electrons from one atom to another (most ionic compounds are salts) |
|
|
anion |
-atom gains one or more electrons -exhibits a negative charge |
|
|
cation |
-atom loses one or more electrons -exhibits positive charge |
|
|
The ____________ results in an ionic bond. |
attraction of opposite charges |
|
|
ions |
atoms that gain or lose electrons and become charged |
|
|
Covalent Bonds |
this bond is formed by sharing two or more electrons |
|
|
Name the two types of covalent bonds |
nonpolar covalent bonds polar covalent bonds |
|
|
Nonpolar Covalent Bonds |
electrons are shared equally |
|
|
Polar Covalent Bonds |
electrons are shared unequally |
|
|
Electronegative |
Small atoms with 6 or 7 valence shell electrons |
|
|
Electropositive |
atoms with 1 or 2 valence shell electrons |
|
|
Hydrogen Bonds |
Attractive force between electropositive hydrogen of one molecule and an electronegative atom of another molecule |
