the type of attraction inside a molecule

Explanation:

• Intermolecular forces are the attractions between molecules. For example, in water, hydrogen bonds (a type of intermolecular force) act between water molecules.
• Electrostatic attraction occurs between the positively - charged nucleus and negatively - charged electrons in an atom. Opposite charges attract each other.
• Chemical bond is the attractive force that binds atoms together in a compound. For instance, in sodium chloride (\(NaCl\)), an ionic bond (a type of chemical bond) holds sodium (\(Na\)) and chlorine (\(Cl\)) atoms together.
• Intramolecular force is the type of attraction inside a molecule. Chemical bonds (like covalent, ionic, or metallic bonds) are intramolecular forces as they act within a molecule to hold its atoms together.

Answer:

• the type of attraction between molecules: intermolecular forces
• the attraction between the nucleus and electrons in an atom: electrostatic attraction
• an attractive force that binds atoms together in a compound: chemical bond
• the type of attraction inside a molecule: intramolecular force
