Question

Atomic nuclei are made of protons and neutrons. Thisshows that there must be another kind of interaction in addition togravitational and electric forces. Explain.

Short answer

Answer

Atomic nuclei are stable.

Step-by-step solution

Definition of the gravity and the electric force

Gravity is a primary interaction that attracts (or gravitates) all entities with mass or energy. For instance, the gases in the sun are held together by gravity.

An electric force is the attracting or repulsive interface between individuals' charged things. For instance, Rubbing the cloth with iron rod.

Describe another kind of interaction in addition to gravitational and electric forces

The Positively charged protons and neutral neutrons make up an atom's nucleus.

Because protons have the same charge, they resist each other (electric force).Because the gravitational force is several times smaller than the electric force, if these were the main forces that existed, atom nuclei would be unstable, to say the least. What the electromagnetic force pushes apart, gravity couldn't retain.

Another force (known as the nuclear force) must bind the positively charged protons and neutrons, rendering the atom's nucleus stable.
