05 Atoms and Bonding

Front

What is a hydrogen bond?

Back

A weak attraction between a hydrogen atom and an oxygen atom in different molecules.

Front

What is the attractive force that holds two atoms together called?

Back

Covalent bond.

Front

In a bond between hydrogen (H) and fluoride (F), what charge does the fluorine end of the molecule have?

Back

Negative.

Front

What are substances made in a chemical reaction called?

Back

Products.

Front

What type of bond is formed when a pair of electrons is shared unequally between two atoms?

Back

Polar covalent bond.

Front

What is the definition of a covalent bond?

Back

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

Front

What is the difference between a polar covalent bond and a nonpolar covalent bond?

Back

A polar covalent bond involves unequal sharing of electrons, while a nonpolar covalent bond involves equal sharing.

Front

What role do electrons play in chemical bonding?

Back

Electrons are involved in the formation of bonds between atoms, either by being shared or transferred.

Front

What is the significance of electronegativity in bond formation?

Back

Electronegativity determines how strongly an atom attracts electrons, influencing bond type (ionic, polar covalent, nonpolar covalent).

Front

What are ionic bonds?

Back

Chemical bonds formed through the transfer of electrons from one atom to another, resulting in the attraction between oppositely charged ions.
