Understanding Lewis Structures and Bonding

Front

What does each line or 'stick' in a Lewis Structure represent?

Back

Each line represents 2 electrons.

Front

How many covalent (shared pairs) bonds does H₂O have?

Back

H₂O has 2 covalent bonds.

Front

What type of bond shares electrons?

Back

Covalent bond shares electrons.

Front

What is the goal of the Lewis Dot Structure?

Back

To show the element's valence electrons & bonding capabilities.

Front

What type of bond is formed between metal atoms?

Back

Metallic bond.

Front

What are valence electrons?

Back

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

Front

What is an ionic bond?

Back

An ionic bond is formed when electrons are transferred from one atom to another, resulting in oppositely charged ions.

Front

What is a covalent bond?

Back

A covalent bond is formed when two atoms share one or more pairs of 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.

Front

How do you determine the number of valence electrons in an element?

Back

The number of valence electrons can be determined by the group number of the element in the periodic table.
