|
|
Ion |
a charged particle that has either more or fewer electrons than protons |
|
|
Ionic bond |
the force of attraction between the opposite charges of the ions in an ionic compound |
|
|
Covalent Bond |
the attraction that forms between atoms when they share electrons |
|
|
Molecule |

|
|
Polar Bond |
a bond in which electrons are shared unequally, resulting in a slightly positive end and a slightly negative end |
|
|
Polar Molecule |
