covalent bond vocab
chem
| Term | Definition |
|---|---|
| Aysmmetrical molecule | A molecule with unequal amount of sharing |
| Bent | when atoms are arranged in a curved shape when central atom has 1 or more ionic pairs. All bent molecules are polar |
| Binary compound | A compound made of 2 or more substances |
| coordinate covalent bond | where both electrons in the shared pair come from the same atom |
| covalent bond | a bond where atoms share electrons causing different types of attractions |
| diatomic molecule | a molecule made of 2 atoms bonded toghther |
| dipole | a slight positive or negative charge by unequal sharing of electrons |
| dipole-dipole force | when positive end of one polar molecule is attracted to the negative side of another molecule |
| dipole-induced-dipole force | when a molecule with permanent dipole and a region of partial negative approaches no polar molecule |
| double covalent bond | 2 bonds formed in an atom that shares 2 pairs of electrons |
| electronegativity | how strong an atom pulls on electrons in a bond |
| hydrogen bond | strongest type of dipole-dipole attraction. Hydrogen directly bonds with N.O.F |
| intermolecular force | how molecules interact in between molecules |
| Ionic bond | a bond between electrons where they are transfered, Nonmetal-Metal |
| linear | when atoms are arranged in a line from a bond. can be polar and nonpolar |
| London Dispersion Force and Van Der Waals forces | weaker force that occurs by temp shifts in electrons that produce momentary dipoles |
| Metallic bond | the attraction between positive metal ions and there is a sea of electrons |
| molecule | A covalently bonded atom |
| multiple covalent bond | when there are many different bonds according to n atom and multiple electrons are shared |
| molecular | covalently bonded molecules ( same thing as molecule) |
| non polar covalent bond | electrons are being shared equally between atoms (ushally between 2 of the same atoms) it occurs due to the electronegativity being equal and cancelling out |
| polar covalent bond | electrons are shared unequally due to one atom pulling on the electron more. |
| pyramidal | 3 sided pyramid setup of molecule. The central atom is at the top and the 3 bonds happen at the base. Ushally always polar |
| symmetrical formula | a symmetrical molecule setup |
| tetrahedral | 4 atoms bonded to a central atom and its evenly spread out. Can be polar and nonpolar |
| triple covalent bond | a bond that shares 3 pairs of electrons |
| vapor pressure | the pressure created when molecules at the surface of a liquid escapes to a gas phase |
