Front

What is a Lewis Dot Structure?

Back

A diagram that shows the bonding between atoms of a molecule and the lone pairs of electrons that may exist in the molecule.

Front

What type of bond is formed when two atoms share electrons?

Back

Covalent bond.

Front

What is an ionic bond?

Back

A type of chemical bond that involves the electrostatic attraction between oppositely charged ions.

Front

What is electronegativity (EN)?

Back

A measure of the tendency of an atom to attract a bonding pair of electrons.

Front

Front

What is a lone pair of electrons?

Back

A pair of valence electrons that are not shared with another atom.
