Lewis Structures

Front

What are Lewis Structures?

Back

Lewis Structures are diagrams that represent the bonding between atoms of a molecule and the lone pairs of electrons that may exist in the molecule.

How many valence electrons are available for bonding in the sulfate ion (SO₄²⁻)?

Back

32 electrons.

Front

How many electrons does each line in a Lewis Structure indicate are shared?

Back

2 electrons.

Front

What is a covalent bond?

Back

A covalent bond is a bond that shares electrons between nonmetals.

Front

According to the octet rule, most elements need how many valence electrons?

Back

8 valence electrons.

Front

How many valence electrons are in Phosphorus?

Back

5 valence electrons.

Front

What is the octet rule?

Back

The octet rule states that atoms tend to bond in such a way that they have eight electrons in their valence shell, achieving a stable electron configuration.

Front

What is a lone pair in a Lewis Structure?

Back

A lone pair is a pair of valence electrons that are not shared with another atom and are not involved in bonding.

Front

What does a double bond represent in a Lewis Structure?

Back

A double bond represents the sharing of two pairs of electrons between two atoms.

Front

What is the significance of valence electrons in bonding?

Back

Valence electrons are the electrons in the outermost shell of an atom and are involved in forming bonds with other atoms.
