| A | B |
|---|
| covalent bond | when electrons are shared between two atoms |
| ionic bond | when electrons are transferred from one atom to another and the resulting charges of the atoms attract |
| hydrogen bond | the partial negative charge of an electronegative atom in a polar bond is attracted to the partial positive charge of hydrogen atom in another polar bond |
| polar covalent bond | when electrons are shared unevenly between two atoms |
| electronegativity | the ability of an atom to attract electrons to itself |
| dipole | a situation where there is a negative pole and a positive pole |
| linear | the shape of carbon dioxide |
| trigonal planar | a flat molecule shape with 3 atoms equally spaced around a central atom, 120 degrees from each other |
| tetrahedral | a molecule shape where 4 atoms are spread out evenly around a central atom |
| bent | the shape of a water molecule |
| VSEPR | the theory that states that electron pairs repel each other and are therefore as far apart as possible in a molecule |
| carbon tetrabromide | tetrahedral shape |
