Covalent Bonds

Front

How do covalent bonds form?

Back

Covalent bonds form by sharing valence electrons between atoms.

Front

What are outer shell electrons called?

Back

Outer shell electrons are called valence electrons.

Front

What does it mean for an atom to have an octet?

Back

It means the atom has gained, lost, or shared electrons resulting in having 8 valence electrons, which provides stability and resembles a Noble Gas.

Front

What is a neutral group of atoms held together by covalent bonds?

Back

A neutral group of atoms held together by covalent bonds is called a molecule.

Front

What is a covalent bond?

Back

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

Front

What is the difference between ionic and covalent bonds?

Back

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

Front

What are diatomic molecules?

Back

Diatomic molecules are molecules composed of only two atoms, which can be of the same or different elements.

Front

What is a polar covalent bond?

Back

A polar covalent bond is a type of covalent bond where the electrons are not shared equally between the two atoms.

Front

What is a nonpolar covalent bond?

Back

A nonpolar covalent bond is a type of covalent bond where the electrons are shared equally between the two atoms.

Front

What is a molecular formula?

Back

A molecular formula shows the number and type of atoms in a molecule, such as H2O for water.
