|
Chemical bonds |
Atoms sharing or transfer valence electrons |
|
|
Colvalent bond |
Sharing of a pair of valence electrons by two atoms |
|
|
Molecule |
Two or more atoms held together by covalent bonds |
|
|
Single bond |
A pair of shared electrons |
|
|
Double bond |
Sharing two pairs of valence electrons |
|
|
Atom's Valence |
Bonding capacity. Usually equal to the number of unpaired electrons required to complete atoms valence shell. |
|
|
Electronegativity |
Attraction of a particular atom for the electrons of a covalent bond |
|
|
Nonpolar covalent bond |
Covalent bond two atoms of the same element. Electrons shared have the same electronegativity. |
|
|
Polar covalent bond |
When an atom is bonded to a more electronegative atom, the electrons of the bond are not shared equally |
|
|
Ions |
Two opposite charged atoms or molecules |
|
|
Cation |
Positivley charged ion (cats are positive, meow) |
|
|
Anion |
Negatively charged ion |
|
|
Ionic bond |
Any two ions of opposite charge can can form this bond. No electron transfer charge required |
