What is the force of attraction between a proton and a proton?
A: The electromagnetic force of repulsion between positively charged protons is overcome by a stronger force, called the strong nuclear force.
What is responsible for attraction or repulsion between subatomic particles?
The subatomic particles in atoms contains charges. Protons are positively charged Electrons are negatively charged and Neutrons carry no charge . Due to the charges present in subatomic particles attraction and repulsion take place between matter.
What does the force of attraction between protons and electrons depend on?
The force of attraction depends on the distance between the proton and electron. … The greater the number of protons, the greater the pull on the electrons, which means greater force.
Is the force repulsion between electrons and protons in an atom?
Electromagnetic force is a force of attraction or repulsion between all electrically charged particles. … Inside the atom, two types of subatomic particles have electric charge: electrons, which have an electric charge of -1, and protons, which have an opposite but equal electric charge of +1.
Why do protons and neutrons attract?
Protons and neutrons are held together in a nucleus of an atom by the strong force. The strong force gets it name by being the strongest attractive force. … And it is the quarks that exchange force carrying particles between each other to give rise to the strong force. The force carrying particles are called gluons.
Which is stronger the strong force or electrical repulsion?
The strong force is approximately 100 times larger than the Coulomb repulsion. You may have heard about subatomic entities called quarks. These are the tiny constituents of neutrons and protons.
Why do electrical forces dominate between atoms that are close together?
because gravity always attracts. … Electrical forces are the dominant forces for atomic-sized objects, since the gravitational forces between tiny objects like protons and electrons are negligible – it takes a BIG object to exert an appreciable gravitational force!
Is electron proton attractive or repulsive?
Explain to students that two protons repel each other and that two electrons repel each other. But a proton and an electron attract each other. Another way of saying this is that the same or “like” charges repel one another and opposite charges attract one another.
What does shielding mean in chemistry?
Electrons in an atom can shield each other from the pull of the nucleus. This effect, called the shielding effect, describes the decrease in attraction between an electron and the nucleus in any atom with more than one electron shell. … The more shielding that occurs, the further the valence shell can spread out.
Are electrons attracted or repelled by the nucleus?
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.
