Unit 4: Test Review- Bonding (23-24)

Front

What is the Lewis dot structure for a diatomic molecule like fluorine (F₂)?

Back

The Lewis dot structure for F₂ shows two fluorine atoms, each with 7 valence electrons, sharing one pair of electrons.

Front

What is a correct dot diagram for a single fluorine atom (F)?

Back

A correct dot diagram for fluorine (F) shows 7 dots around the symbol, representing its 7 valence electrons.

Front

What is the formula for the ionic bond formed between strontium and oxygen?

Back

The formula for the ionic bond between strontium and oxygen is SrO.

Front

What is a triple bond in terms of electron sharing?

Back

A triple bond occurs when three pairs of electrons are shared between two atoms.

Front

How can you identify if a compound is ionic or covalent?

Back

A compound is ionic if it consists of a metal and a non-metal, while it is covalent if it consists of two non-metals.

Front

What are valence electrons and why are they important in bonding?

Back

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

Front

What is the difference between ionic and covalent bonds?

Back

Ionic bonds involve the transfer of electrons from one atom to another, while covalent bonds involve the sharing of electrons between atoms.

Front

What is the significance of the octet rule in chemical bonding?

Back

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

Front

How do you determine the type of bond between two elements?

Back

The type of bond can be determined by the difference in electronegativity between the two elements: a large difference indicates ionic, while a small difference indicates covalent.

Front

What is a dot diagram and how is it used in chemistry?

Back

A dot diagram, or Lewis structure, visually represents the valence electrons of an atom and helps in understanding how atoms bond.
