Types of Chemical Bonds

Front

Type of bond that involves the transfer of electrons from one atom to another

Back

Ionic bond

Front

Type of bond that occurs when atoms share electrons

Back

Covalent bond

Front

In metallic bonding, electrons are best described as

Back

Free-moving in a “sea of electrons”

Front

Property of ionic compounds

Back

Brittle crystalline solids

Front

Property of covalent compounds

Back

Generally low melting and boiling points

Front

Property most closely associated with metallic compounds

Back

Good conductors of heat and electricity

Front

Electronegativity is defined as

Back

The ability of an atom to attract electrons in a bond

Front

If the difference in electronegativity between two atoms is large (greater than 1.7), the bond is usually

Back

Ionic

Front

A polar covalent bond occurs when electrons are shared unequally.

Back

A polar covalent bond has a partial positive charge on one atom and a partial negative charge on another.

Front

A nonpolar covalent bond occurs when electrons are shared equally between atoms.

Back

In a nonpolar covalent bond, the electron density is evenly distributed.
