Covalent Bonding & Classifying Bonds

Front

What is a covalent bond?

Back

A covalent bond is a chemical bond formed when two nonmetal atoms share one or more pairs of electrons.

Front

What is a polar covalent bond?

Back

A polar covalent bond is a type of bond where the shared electrons are closer to one atom due to a difference in electronegativity.

Front

What is an ionic bond?

Back

An ionic bond is a chemical bond formed between a metal and a nonmetal, where electrons are transferred from one atom to another.

Front

What is electronegativity?

Back

Electronegativity is a measure of an atom's ability to attract and hold onto electrons in a chemical bond.

Front

What type of bond is formed between two nonmetals?

Back

A covalent bond is formed between two nonmetals.

Front

What is the difference in electronegativity for a nonpolar covalent bond?

Back

The difference in electronegativity for a nonpolar covalent bond is typically 0.0 to 0.4.

Front

What is the difference in electronegativity for a polar covalent bond?

Back

The difference in electronegativity for a polar covalent bond is typically 0.4 to 1.7.

Front

What is the difference in electronegativity for an ionic bond?

Back

The difference in electronegativity for an ionic bond is typically greater than 1.7.

Front

How do you classify the bond between sulfur and selenium?

Back

The bond between sulfur and selenium is classified as a nonpolar covalent bond.

Front

What happens to shared electrons in a polar covalent bond?

Back

In a polar covalent bond, the shared electrons are pulled closer to the atom with higher electronegativity.
