Covalent Bond Review

Front

What is a covalent bond?

Back

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

Front

What determines the polarity of a molecule?

Back

The polarity of a molecule is determined by the difference in electronegativity between the atoms and the shape of the molecule.

Front

What is electronegativity?

Back

Electronegativity is a measure of an atom's ability to attract and hold onto 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, resulting in slight charges.

Front

What is a non-polar covalent bond?

Back

A non-polar covalent bond is a bond where electrons are shared equally between two atoms, resulting in no charge separation.

Front

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

Back

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

Front

How do you identify a polar molecule?

Back

A polar molecule has a net dipole moment due to the presence of polar bonds and an asymmetrical shape.

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.

Front

What is a molecule?

Back

A molecule is a group of two or more atoms bonded together by covalent bonds.

Front

What is the role of valence electrons in covalent bonding?

Back

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