Chemical Bonding

Allotope

One of two more different forms of an element in the same phase. EX: Oxygen-02 and Ozone 03

Anion

A negatively charged ion

Asymmetrical molecule

A molecule that lacks identical atomic structure on each side of the axis

Cation

A positively charged ion

Diatomic molecule

A nonmetal atom that forms one or more nonpolar covalent bonds with another atom of the same element to form a molecule consisting of the two atoms when there is no other to bond with. Elements that do this Br

Double Covalent Bond

The sharing of two pairs of electrons between two nuclei?

Electronegativity

A measure of the attraction of a nucleus for a bonded electron

Hydrogen Bond

The attraction of hydrogen atom in one molecule for an oxygen

Ion

A charged bond

Ionic Bond

A bond formed when a metal atom loses its valence electrons to a nonmetal atom

Ionization Energy

The amount of energy needed to remove the most loosely bound electrons from a neutral gaseous atom

Lewis Dot Diagram

A diagram that depicts valence electrons as dots around the atomic symbol

Metallic Bond

Molecule

The smallest unit of a covalently bonded substance that has the properties of that substance

Molecular Orbit

A hybrid orbital made up of the shared unpaired valence electrons of two nonmetallic atoms. The orbital belongs to both of the bonded atoms rather than to any specific atom

Monatomic molecule

An atom of noble gas

Multiple Covalent Bonds

A double or tripe covalent bond

Nonpolar Covalent bond

A bond formed between two nonmetal atoms when unpaired electrons of two atoms are shared equally

Nonreactive

Not capable of readily undergoing a chemical change.

Polar Covalent Bonds

A bond formed between two nonmetal atoms when unpaired electrons of two atoms are shared unequally with an electronegative difference of 0.1-1.6

Polyatomic ion

A covalently bonded group of atoms that have a net electric charge

Reactive

Capable of readily undergoing a chemical change.

Single Covalent Bond

Only one pair of electrons is shared between two atoms

Symmetrical Molecule

A molecule with identical atomic structure on each side of the axis

Triple Bond

The sharing of three pairs of electrons between two nuclei
