# What is responsible for the attraction or repulsion of electrons or protons?

Contents

## What causes the attraction between protons and electrons?

(The electrons are attracted to the nucleus because the nucleus has positively charged protons in it. This coulombic attraction causes electrons to orbit around the nucleus.) The strength of the coulombic attraction depends on two things: … The total charge of the atom.

## Is there attraction or repulsion between protons and electrons?

Electromagnetic Force of Attraction: exists between negative electrons and positive protons in the nucleus and keeps electrons in the area surrounding the nucleus. Electromagnetic Force of Repulsion: exists between positive protons in the nucleus is overcome by the strong nuclear force between protons and neutrons.

## What causes attraction and repulsion between atoms?

A simplistic answer is electrostatic charges. Unpaired electrons cause atoms with them to attract one another. However, the basic explanation then says they get close to each other but not closer because of the electrostatic repulsion between nuclei.

## Which of the four forces causes the repulsion that protons have for each other?

Inside the nucleus, the attractive strong nuclear force between protons outweighs the repulsive electromagnetic force and keeps the nucleus stable. Outside the nucleus, the electromagnetic force is stronger and protons repel each other.

## What is the attraction or repulsion between electric charges?

The attraction or repulsion between charged particles is called electric force. The strength of electric force depends on the amount of electric charge on the particles and the distance between them. Larger charges or shorter distances result in greater force.

## Is proton proton attractive or repulsive?

The electrostatic charge of protons contributes a repulsive force, but at sufficiently small separation distances the nuclear strong force is supposedly greater in magnitude than the electrostatic force and thus an attraction can result.

## What happens when an electron and a proton get close together?

That is, a proton and an electron will attract each other. The closer they are together, the stronger this attraction will be. Two protons (or two electrons) will repel each other. And again, the closer together they are, the stronger the repulsion.

## Why do protons and neutrons attract?

The strong nuclear force pulls together protons and neutrons in the nucleus. At very small distances only, such as those inside the nucleus, this strong force overcomes the electromagnetic force, and prevents the electrical repulsion of protons from blowing the nucleus apart.

## What causes repulsion?

In contrast to the attractive force between two objects with opposite charges, two objects that are of like charge will repel each other. That is, a positively charged object will exert a repulsive force upon a second positively charged object. This repulsive force will push the two objects apart.

## What is attraction and repulsion force?

Repulsion is a movement between two charges that are identical or similar. The power that exists between two electrons (negative charge). Attraction is a force between two charges that are distinct or unlike. … Repulsive forces occur only when atoms are very close to each other.

## What does electron repulsion do in bond formation?

ii) The repulsion between electron pairs increases with increase in electronegativity of central atom and hence the bond angle increases. The bond pairs are closer and thus by shortening the distance between them, which in turn increases the repulsion. Hence the bonds tend to move away from each other.

## What forces attract atoms?

Oppositely charged particles attract each other, while like particles repel one another. Electrons are kept in the orbit around the nucleus by the electromagnetic force, because the nucleus in the center of the atom is positively charged and attracts the negatively charged electrons.

## What are the 4 forces of the universe?

fundamental force, also called fundamental interaction, in physics, any of the four basic forces—gravitational, electromagnetic, strong, and weak—that govern how objects or particles interact and how certain particles decay. All the known forces of nature can be traced to these fundamental forces.

## Which force has a role in atomic decay?

weak interaction, also called weak force or weak nuclear force, a fundamental force of nature that underlies some forms of radioactivity, governs the decay of unstable subatomic particles such as mesons, and initiates the nuclear fusion reaction that fuels the Sun.
