|
|
|
What is an ion? |
charged particles that have either more or fewer electrons than protons |
|
|
|
Ionic bond? |
force of the attraction between the opposite charges of the ions in a compound |
gain or lose |
|
|
Covalent bond? |
the attraction that forms between atoms when they share electrons |
Coexist |
|
|
Multiple Covalent Bonds? |
when two pairs of electrons represent two bonds |
|
|
|
Non-polar Bonding? |
Covalent bond that shares electrons equally by both atoms |
