Answer:
Fr⁺ and P₃⁻ have an electrostatic force of attraction between them.
Step-by-step explanation:
Atoms that are present in all bodies, are composed of electrons, protons and neutrons. All three have mass, but only the electron and the proton have charge. The electron has a negative charge, and the proton has a positive charge.
The electromagnetic force in this case is the interaction that occurs between atoms that have an electric charge. When the charges are at rest, the interaction between them is called electrostatic force. Depending on the sign of the charges that interact, electrostatic force can be attractive or repulsive.
The electrostatic interaction between charges of the same sign is repulsive (two negative charges or two positive charges), while the interaction between charges of the opposite sign (a negative charge and a positive charge) is attractive. In the case of neutral charges against negative or positive charges, no force is generated.
Taking into account everything mentioned above, it is possible to say that Fr⁺ and P₃⁻ have an electrostatic force of attraction between them.
