A particle with zero charge found in the nucleus of an atom is the?
Neutron Found in the nucleus of atoms.
What happens to a positively-charged alpha particle directly hits the positively-charged nucleus?
When a positively-charged alpha particle directly hits a positively-charged nucleus, it experiences a strong electrostatic repulsion due to the like charges. This repulsion can cause the alpha particle to be deflected away from the nucleus, preventing it from penetrating further. If the energy of the alpha particle is high enough, it may overcome the repulsive force, resulting in nuclear reactions or the emission of radiation, but typically, it is repelled.
What happens when the positively charged alpha particle directly hits the positively charged nuckeus?
When a positively charged alpha particle collides with a positively charged nucleus, they experience a strong repulsive force due to their like charges. This repulsion can prevent the alpha particle from penetrating the nucleus. If the energy of the alpha particle is sufficiently high, it may overcome the Coulomb barrier and interact with the nucleus, potentially leading to nuclear reactions such as fusion or scattering. However, under normal circumstances, the alpha particle will simply be deflected away from the nucleus.
What is The repulsive force between proton-proton pairs inside the nucleus is called the?
The repulsive force between proton-proton pairs inside the nucleus is called the electrostatic repulsion force. This force arises due to the positively charged protons within the nucleus experiencing mutual repulsion because they all have the same charge.
Which particle is bigger Ca or Ca2 plus?
The particle Ca2+ is bigger in size compared to the Ca particle. This is because Ca2+ has an additional charge compared to Ca, which results in a larger ionic radius due to increased electron-electron repulsion that can overcome the attractive force between the nucleus and electrons.
What is an uncharged particle in the nucelues?
Neutrons are Neutral. (They don't have a charge.)
Why is it easier to hit a nucleus with a neutron rather than an alpha particle?
Neutrons are uncharged; alpha particles have a charge of +2. That means that while there is no electrostatic repulsion between the nucleus and the neutron, the alpha particle is repelled by the (also positively charged) nucleus.
A positively charged particle has great difficulty penetrating a target nucleus because the target nucleus has what?
A positively charged particle has great difficulty penetrating a target nucleus because of the strong repulsive electrostatic force between the positively charged particle and the positively charged protons in the nucleus. This repulsion acts as a barrier that prevents the particle from approaching the nucleus closely.
Which particle is responsible for holding the nucleus together?
The particle responsible for holding the nucleus together is the strong nuclear force mediated by particles called gluons. This force overcomes the electrostatic repulsion between positively charged protons within the nucleus, keeping it stable.

Neutron Found in the nucleus of atoms.

If an particle hits a gold nucleus in a head on collision the particle will not be deflected very much?
Correct, due to the massive size of the gold nucleus compared to the size of the incoming particle, the particle will not experience a large deflection in a head-on collision. This is because of the concentrated positive charge in a small space in the gold nucleus that causes a very strong Coulomb repulsion when the incoming particle gets close to it.
What force is responsible for the stability of a particle?
The strong nuclear force is responsible for the stability of particles like protons and neutrons within the atomic nucleus. This force is attractive and acts to overcome the repulsion between positively charged protons, holding the nucleus together.
The force of repulsion between protons in the nucleus of small atoms is?
Less than
What is the approximate distance between an electron and the nucleus?
The Bohr radius, is the estimated distance between protons in the nucleus and electrons - but electrons aren't solid, stationary particles... The simple answer would be about one-twentieth of a nanometre. But this would only be reasonable if the electron were a solid particle.
How are electrons held in orbit in their atoms?
Between electrons and the atomic nucleus a repulsion exist.
Force that affects all particles in a nucleus and acts only over a short range?
It is the strong nuclear force that holds the particles together in the nucleus. It is far stronger than the electromagnetic force over short ranges (particle separations of up to 2.5x10-15m), and so can overcome the repulsion that occurs between protons in the nucleus (typical distance approximately 1.25x10-15m) as a result of their positive charges.
