Ch 6 Review Honors

Front

What elements can form multiple covalent bonds?

Back

Carbon (C), Nitrogen (N), and Oxygen (O) can form multiple covalent bonds.

Front

How do you account for electrons when drawing a Lewis Structure for an ion?

Back

Add one electron for each unit of negative charge.

Front

What is the formal charge of oxygen when it is double bonded to one element and has two lone pairs?

Back

The formal charge of oxygen is zero.

Front

What is not necessary to know when drawing a Lewis Dot Structure?

Back

Bond energies are not necessary to know.

Front

Which molecule contains a polar covalent bond but is a non-polar molecule?

Back

Carbon dioxide (CO2) contains a polar covalent bond but is non-polar.

Front

Define a covalent bond.

Back

A covalent bond is a chemical bond that involves the sharing of electron pairs between atoms.

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 bonding?

Back

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

Front

What is a polar covalent bond?

Back

A polar covalent bond is a type of bond that occurs when two atoms share electrons unequally, resulting in a molecule with a slight electrical dipole moment.

Front

What is the octet rule?

Back

The octet rule states that atoms tend to form bonds until they are surrounded by eight valence electrons.
