Bonding and Lewis structures

Front

What is a covalent compound?

Back

A covalent compound is a chemical compound formed by the sharing of electrons between atoms.

Front

What is an example of an ionic compound?

Back

NaCl (sodium chloride) is an example of an ionic compound.

Front

What is the electronegativity difference for a nonpolar covalent bond?

Back

The difference in electronegativity must be less than 0.4.

Front

What type of bond is present in a nitrogen molecule (N2)?

Back

A nitrogen molecule (N2) has a triple covalent bond.

Front

What is a characteristic property of ionic compounds?

Back

Ionic compounds form hard, brittle crystals with characteristic shapes.

Front

What is the definition of electronegativity?

Back

Electronegativity is a measure of the tendency of an atom to attract a bonding pair of electrons.

Front

What type of bond involves the transfer of electrons?

Back

Ionic bonds involve the transfer of electrons.

Front

What is a polar covalent bond?

Back

A polar covalent bond is a type of bond where electrons are shared unequally 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.

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.
