AB
bond angleangle formed by 2 atoms attached to the central atom in a molecule
bonding electronsvalence electrons in a molecule that are shared
chemical bondattraction between 2 ions & 2 atoms
coordinate covalent bondbond in which an electron pair is shared but both electrons have been donated by a single atom
diatomic moleculemolecule made up of 2 nonmetal atoms held together by a covalent bond
double bondbond made up of 2 shared electron pairs between 2 atoms
electron dot formuladiagram of a molecule which @ atom is surrounded by 2 dots for @ pair of bonding or nonbonding electrons
electronegativityability of an atom to attract a shared pair of electrons
formula unitsimplest representative particle in a substance held together by ionic bonds
ionic bonda chemical bond characterized by the attraction between a cation and anion
molecular shapethe geometric shape formed by atoms bonded to a central atom in a molecule
moleculesimplest representative particle in a substance held together by covalent bonds
nonbonding electronvalence electrons in a molecule that are not shared
nonpolar bonda bond in which a pair of electrons is shared equally
octet rulean atom must be surrounded by 8 valence electrons to be stable
polar bondbond in which a pair of electrons is shared unequally
polyatomic iongroup of atoms held together by covalent bonds that has an overall positive or negative charge
single bonda bond of one shared electron pair between 2 atoms
structural formuladiagram of a molecule which each atom is represented by its chemical symbol and a dash for each pair of bonding electrons
triple bonda bond made up of 3 shared electron pairs between 2 atoms
valence electronsthe electrons in the outermost energy level that are available for bonding
covalent bonda chemical bond which shares one or more pairs of valence electrons
