Question

what have we figured out about attractions between oppositely charged particles?

Explanation:

According to Coulomb's law, the force of attraction between oppositely - charged particles is directly proportional to the product of their charges and inversely proportional to the square of the distance between them. This force is responsible for many chemical and physical phenomena such as the formation of ionic bonds.

Answer:

The force of attraction between oppositely - charged particles is described by Coulomb's law, which states it is proportional to the product of charges and inversely proportional to the square of the distance between them, and it plays a key role in chemical bonding and other physical and chemical processes.
