Covalent Bonding Flashcard

Front

What is the octet rule?

Back

Atoms gain, lose, or share electrons until they can get to 8 electrons.

Front

Front

What is a characteristic of a nonpolar covalent bond?

Back

The electrons are mostly evenly distributed.

Front

Sharing of electrons.

Front

What is a covalent bond?

Back

A chemical bond formed by the sharing of electrons between atoms.

Front

What is the difference between ionic and covalent bonds?

Back

Ionic bonds involve transfer of electrons, while covalent bonds involve sharing of electrons.

Front

What are valence electrons?

Back

Electrons in the outermost shell of an atom that are involved in chemical bonding.

Front

What is a polar covalent bond?

Back

A covalent bond where the electrons are shared unequally between atoms.

Front

What is the significance of electronegativity in covalent bonding?

Back

Electronegativity determines how strongly an atom attracts shared electrons.
