What is the only force that can overcome the repulsion between two positively charged nuclei to bind into an atomic nucleus?
The strong nuclear force is the only force that can overcome the repulsion between positively charged nuclei to bind them together in an atomic nucleus. This force is one of the four fundamental forces in nature, and it is responsible for holding the nucleus together by acting between particles called nucleons (protons and neutrons).
Why is a large amount kinetic energy required to force nuclei together?
A large amount of kinetic energy is required to force nuclei together because nuclei are positively charged and repel each other due to electromagnetic forces. Overcoming this repulsion requires a significant amount of energy to bring the nuclei close enough for the strong nuclear force to take effect and bind them together in a nuclear reaction.
What force keeps the nucleus together?
The strong nuclear force is the force that keeps the nucleus of an atom together. This force is stronger than the electromagnetic force, which tends to repel positive protons from each other in the nucleus.
Why are collisions between the nuclei difficult to achieve?
Atomic nuclei usually have a positive charge, so they will tend to repel each other. A neutron on the other hand, carries no charge and may easily interact with either the electron shells, or with the nucleus.
Why is extremely high pressure required to cause atomic nuclei to crash into one another?
Extremely high pressure is required for fusion to occur because the electromagnetic force would otherwise cause the protons in the two nuclei to repel each other, and you need to overcome that repulsive force, and allow the stronger1 binding energy to take over.Not asked, but answered for completeness; you also need extremely high temperature because you need to strip the electron clouds away, i.e. to fully ionize the nuclei, to eliminate interference from the electrons as well.-------------------------------------------------------------------------------------------------1 The binding energy is stronger, but only at closer distances. Outside the radius of the nucleus, the electromagnetic force is more powerful, hence the need for pressure. Once inside the radius of the nucleus, at least for elements smaller than lead, the binding energy is more powerful.
What intermolecular force acts within a metal wire?
The forces which hold a metal together are called metallic bonds. They consist of delocalised electrons which bind all the atoms together.
How many hydrogen atoms would you expect to bind with an atom with 4 valence electrons?
4

How do two atoms of oxygen bind together?
Two atoms of oxygen bind together through a covalent bond, where they share electrons to achieve a stable electron configuration. Each oxygen atom has six outer electrons in its valence shell and needs to gain two more electrons to have a full octet, so they share two electrons with each other, forming a double bond.
Why is a large amount kinetic energy required to force nuclei together?
A large amount of kinetic energy is required to force nuclei together because nuclei are positively charged and repel each other due to electromagnetic forces. Overcoming this repulsion requires a significant amount of energy to bring the nuclei close enough for the strong nuclear force to take effect and bind them together in a nuclear reaction.
What is the force that holds atoms together called?
The question is ambiguous.The primary force between distinct atoms that holds them together is the electromagnetic force (there's also gravity, but that's much much weaker). The communicating particle (aka "gauge particle") for the electromagnetic force is the photon.Several forces play a part in holding an individual atom together. Electrons are bound to the nucleus by the electromagnetic force. The individual nucleons (protons and neutrons) are composed of quarks held together by the strong nuclear (or "color") force, and the nucleons are bound together in the nucleus by the residual strong nuclear force. The gauge particle for the strong force is known as the gluon.
Do atoms of all elements bind the same way?
No, different atoms make chemical bonds in different ways. They may form chemical bonds by either loosing or accepting electrons, sharing or by mutual sharing electrons.
When hydrogen and oxygen bind to one another the electrons are pulled?
When hydrogen and oxygen bind to form water, the electrons are shared between the hydrogen and oxygen atoms. This sharing creates a stable covalent bond in the water molecule.
Why must there be an attractive force to explain existence of stable nuclei?
Nuclei are made of protons (positively charged), plus neutrons (no charge) Positively charged particles repel each other, so there must be another force preventing them from flying apart. That's why there must be an attractive force.
What conditions do you need to get two atoms to fuse?
Depends which atoms you're trying to fuse together.You need to get the nuclei really close, despite the fact they repel each other. This is more likely at high temperatures and pressures. (the exact detail will vary by element)
What force keeps the nucleus together?
The strong nuclear force is the force that keeps the nucleus of an atom together. This force is stronger than the electromagnetic force, which tends to repel positive protons from each other in the nucleus.
Do neutrons in the atoms nucleus keep two or more protons from moving apart?
Yes, neutrons help bind protons together in the nucleus through the strong nuclear force. This force overcomes the electrostatic repulsion between positively charged protons, preventing them from moving apart due to their mutual repulsion.
