Two molecules
Two ions
Two atoms
Two metal particles
Answer is Wrong!
Answer is Right!
The correct answer is: C. Two atoms
A field of force can exist between two atoms because they have electric charges. The electric charges of the atoms can attract or repel each other, depending on their signs.
Option A is incorrect because molecules are made up of atoms. The field of force between two atoms is what holds the molecule together.
Option B is incorrect because ions are atoms that have lost or gained electrons. The field of force between two ions is what holds them together in an ionic bond.
Option D is incorrect because metal particles are made up of atoms. The field of force between two metal particles is what allows them to conduct electricity.
