Terms in this set (25)
negatively charged ion
positively charge ion
symbols and subscripts that represent atoms or ions in a compound.
valence electrons shared by atoms.
polar molecules of the opposite charge that are attracted to one another.
weak dipole bonding caused by a momentary polarization of non polar molecules.
sharing of 2 pairs of electrons with 2 atoms
an elements ability to attract electrons in a bond.
attraction between a partially positive H atom and a strong electronegative F, O, or N atom.
atom or atoms having an electrical charge cause loss/gain or electrons
difference between # portions - positive and # electrons- negative.
a positive/negative compound held together by ionic bonds
noble gas arrangement attained by sharing electrons - combination of atoms.
smallest unit of 2+ atoms held together by covalent bond
nonpolar covalent bond
colavent bond with lecterns sharing equally between atoms
molecule with only non polar bonds or bond dipoles cancel.
set of 8 valence electrons.
Elements in Groups 1A-7A, react to produce a noble gas arrangement with usually 8 electrons in the outer shell.
polar covalent bond
covalent bond were electrons are shred unequally between atoms
molecule containing bond dipoles that do not cancel
unequal sharing of electrons by the difference in electonegativities.
overall electrical charge of covalently bonded nonmetal atoms
sharing of 3 pairs of electrons by 2 atoms
valence shell electron-pair repulsion (VSEPR)
theory that predicts the shape of a molecule b placing electron pairs on a central atom very far apart to minimize the mutual repulsion of the electrons.
seperation of positive/negative charges in a polar bond identified by ⇌
