Lewis Dot Structures, Covalent and Ionic

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 is an ionic bond?

Back

A type of chemical bond that occurs when electrons are transferred from one atom to another, resulting in the formation of charged ions.

Front

What is a covalent bond?

Back

A type of chemical bond where two atoms share one or more pairs of electrons.

Front

How do you determine the central atom in a Lewis Dot Structure?

Back

The central atom is usually the one that needs the most valence electrons or is less electronegative.

Front

What are valence electrons?

Back

The electrons in the outermost shell of an atom that are involved in forming bonds.

Front

Where are nonmetals located on the periodic table?

Back

Nonmetals are typically found on the right side of the periodic table.

Front

What is the octet rule?

Back

The principle that atoms tend to bond in such a way that they have eight electrons in their valence shell.

Front

What is the difference between a polar and nonpolar covalent bond?

Back

A polar covalent bond has unequal sharing of electrons, while a nonpolar covalent bond has equal sharing.

Front

What is electronegativity?

Back

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

Front

What is a molecule?

Back

A group of atoms bonded together, representing the smallest fundamental unit of a chemical compound.
