bonding
Term | Definition |
---|---|
bonds | holds atoms together |
covalent bonds | bond formed by sharing electrons between two nuclei |
ionic bonds | bond formed by the transfer of electrons from one atom to another |
asymmetrical molecules | a molecule that lacks identical atomic structure on each side on of an axis |
dipole-dipole forces | FORCE OF ATTRACTION |
double covalent bond | sharing of two pairs of electrons between two nuclei |
hydrogen bond | the attraction of a hydrogen atom in one molecule for a nitrogen, oxygen,or fluorine atom in another molecule. ( 7,8,9) |
ion | an atom which has gained or lost electrons. a charged particle |
Lewis dot diagram | LED a diagram that depicts valence electrons as dots around the atomic symbol. |
malleability | a metallic property that allows them to be hammered into shape |
metallic bond | the attraction of valence electrons for the positive kernels of metallic atoms, a mobile sea of electrons |
multiple covalent bond | a double or triple covalent bond |
nonpolar covalent bond | bond formed by the equal sharing of a pair of electrons between two nuclei |
octet | stable valence electron configuration of 8 electrons |
octet rule | the atoms generally react by gaining, losing or sharing electrons in order to achieve a complete octet of eight valence electrons - the configuration of a noble gas. |
polar covalent bond | a bond formed by the unequal sharing of electrons between two nuclei |
symmetrical molecules | a molecule with identical atomic structure on each side of the axis. |
triple covalent bond | the sharing of three pairs of electrons between two nuclei. |
valence electrons | electrons in the outer most energy level of an atom |
