A neutral group of atoms joined together by covalent bonds

A molecule consisting of two atoms

A compound that is composed of molecules. (covalently bonded)

A chemical formula of a compound that shows the kinds and numbers of atoms present in a molecule of a compound

A bond formed when two atoms share a pair of electrons

The type of chemical formula that shows the arrangement of atoms in a molecule

A pair of valence electrons that is not shared between atoms

A bond in which two atoms share two pairs of electrons

A covalent bond in which one atom contributes both bonding elements

The energy that is required to break the bond between two covalently bonded atoms

An orbital that applies to the entire molecule

A molecular orbital that can be occupied by two electrons of a covalent bond

A bond formed when two atomic orbitals combine to form a molecular orbital that is symmetrical around the axis connecting the two atomic nuclei

A covalent bond in which the bonding electrons are most likely to be found in sausage-shaped regions above and below the bond axis of the bonded atoms

A bond angle of 109.5 that results when a central atom forms four bonds directed toward the center of a regular tetrahedron

because electron pairs repel, molecules adjust their shapes so that valence electron pairs are as far apart as possible

The resulting orbitals of hybridization of an s and a single p orbital

A covalent bond between atoms of significantly different electronegativities.

A type of intermolecular interaction important in determining the properties of water and of important biological molecules such as proteins and DNA.
