Ch. 8 Covalent Bonds - vocab

bonds formed from the sharing of valence electrons
structural formula
an expanded molecular formula showing the arrangement of atoms within the molecule
two or more atoms held together by covalent bonds
VSEPR model
Valence Shell Electron Pair Repulsion model, which is based on an arrangement that minimizes the repulsion of shared and unshared pairs of electrons around the central atom
coordinate covalent bond
a covalent bond in which one atom contributes both bonding electrons a.k.a dative covalent bond
the combining of two or more atomic orbitals of similar energies on the same atom to produce new orbitals of equal energies
any acid that contains oxyanions
a measure of the ability of an atom in a chemical compound to attract electrons
sigma bond
a single covalent bond that is formed when an electron pair is shared by the direct overlap of bonding orbitals
polar covalent
unequal sharing of electrons
pi bond
formed when parallel orbitals overlap to share electrons
covalent bond
chemical bond that forms when two atoms share electrons
the bonding in molecules or ions that cannot be correctly represented by a single Lewis structure
reaction or process which absorbs energy
reaction or process which releases energy
