Both intra- and intermolecular forces are considered what kind of attraction? Gravitational Coulombic Nuclear None of these answers

## Step 1<br />Intra- and intermolecular forces are the forces of attraction that hold molecules together. These forces are not gravitational, as gravitational forces are the forces of attraction between large bodies, such as planets and stars.<br /><br />## Step 2<br />These forces are also not nuclear, as nuclear forces are the forces that hold the nucleus of an atom together.<br /><br />## Step 3<br />The forces that hold molecules together are known as Coulombic forces. These forces are the result of the attraction between positively charged protons in the nucleus and negatively charged electrons in the electron cloud.
