Chemistry Bonding and Compounds

Front

ionic bonding

Back

chemical bonding that results from the electrical attraction between large numbers of cations and anions

Front

covalent bonding

Back

results from the sharing of electron pairs between two atoms

Front

nonpolar covalent bond

Back

a covalent bond in which the bonding electrons are shared equally by the bonded atoms, resulting in a balanced distribution of electrical charge

Front

polar covalent bond

Back

a covalent bond in which electrons are not shared equally

Front

molecule

Back

the simplest structural unit of an element or compound

Front

molecular compound

Back

a chemical compound whose simplest units are molecules

Front

chemical formula

Back

a representation of a substance using symbols for its constituent elements

Front

bond energy

Back

the energy required to break a chemical bond and form neutral isolated atoms

Front

octet rule

Back

states that atoms lose, gain or share electrons in order to acquire a full set of eight valence electrons

Front

expanded valence

Back

atoms gain more than 8 valence electrons
