Unit 5 Review

Front

What type of electrons are used when writing Lewis Structures?

Back

Valence electrons are used when writing Lewis Structures.

Front

How many pairs of electrons are shared in a triple bond?

Back

Three pairs of electrons are shared in a triple bond.

Front

What is the correct Lewis structure for hydrogen cyanide (HCN)?

Back

The correct Lewis structure for HCN includes a triple bond between carbon and nitrogen, and a single bond between carbon and hydrogen.

Front

Is this a correct dot diagram for oxygen (O): O: ?

Back

False. The correct dot diagram for oxygen should have six valence electrons represented as two pairs and two single dots.

Front

How would you draw a Lewis dot diagram for Magnesium?

Back

The Lewis dot diagram for Magnesium should show two dots representing its two valence electrons.

Front

What is a Lewis Structure?

Back

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

Front

What is the significance of valence electrons in chemical bonding?

Back

Valence electrons determine how an atom can bond with other atoms, influencing the molecule's structure and properties.

Front

What is a single bond in terms of electron sharing?

Back

A single bond involves the sharing of one pair of electrons between two atoms.

Front

What is a double bond in terms of electron sharing?

Back

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

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.
