Covalent bonds and compounds

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 is a polar molecule?

Back

A polar molecule is a molecule that has a partial positive charge on one end and a partial negative charge on the other end due to unequal sharing of electrons.

Front

What is a non-polar molecule?

Back

A non-polar molecule is a molecule that has an even distribution of electrical charge, meaning it does not have distinct positive or negative poles.

Front

How do covalent bonds differ from ionic bonds?

Back

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

Front

What determines if a molecule is polar or non-polar?

Back

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

Front

Which element is most likely to form a covalent bond with hydrogen?

Back

Chlorine (Cl) is most likely to form a covalent bond with hydrogen.

Front

What is a single covalent bond?

Back

A single covalent bond is formed when two atoms share one pair of electrons.

Front

What is a double covalent bond?

Back

A double covalent bond is formed when two atoms share two pairs of electrons.

Front

What is electronegativity?

Back

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

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 have eight electrons in their valence shell, achieving a stable electron configuration.
