The force that binds electrons to nuclei to form atoms is usually called the electrostatic force or the Coulomb force; the magnitude of the force can be calculated using Coulomb's law.

What is the only force that can overcome the repulsion between two positively charged nuclei to bind into an atomic nucleus?
The strong force.
What force keeps the nucleus together?
The inter nuclear forces bind the atoms and nucleus together . This force is the cause for the nucleus binded towards the atoms.
How radiation takes place?
Naturally occurring radiation is because of the instability of the nuclei of some atoms. The nucleus of an atom contains protons and neutrons, or positive and neutral particles. These positive particles are constantly repelling each other, but bind energy holds the nucleus together. The particles in the nucleus are not stationary, but are moving around. This can sometimes cause the instability to increase and 'throw' out some of the particles. This is radioactive decay.
Why are viscous forces electromagnetic in nature?
Physics does not answer the 'why' questions, it's the job of Philosophy. However if you'd ask how viscosity is connected to electromagnetic force then I could tell you the following: in 0 Kelvin electromagnetic force between electrons and protons is 0 - at lest publications on the Internet point to such conclusion. That is why magnetic field has no effect on superconductors in 0 K. Once you start adding energy and hence raise the temperature above 0 K the atom is forced to higher energy levels and this manifests in non-zero electromagnetic force. Once you get even minute electromagnetic force it causes "drag" on flow of electrons which on macroscopic level can be observed as viscosity in fluids and electric resistance in classical conductors. It's the electromagnetic force that is the cause of viscosity and once the energy is drained from the system, temperature and electromagnetic force drops to 0 so electrons bind in Cooper pairs and do not interact strongly with protons. If someone can give me an example of an experiment that disproves the above then by all means please let me know: n074v41l4vl34u {at> gmail <dot} com
What are the 3 properties of subatomic particles?
Electrons and Protons and Neurons make up an atom. An atom can form a compound or molecule when it reacts chemically with another atom. It is the outer layers' valence electrons which cause hte reaction.
What is the only force that can overcome the repulsion between two positively charged nuclei to bind into an atomic nucleus?
The strong force.
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
What force keeps the nucleus together?
The inter nuclear forces bind the atoms and nucleus together . This force is the cause for the nucleus binded towards the atoms.
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.
Nuclear fusion causes what to form?
Fusion happens when an electromagnetic force normally preventing fusion is overcome. The electromagnetic force exists because the nuclei of atoms are positively charged. They are rather like identical poles of magnets that want to repel each other. Fusion takes place when something overcomes this and pushes them into each other, at which point, the more powerful strong nuclear force can bind them. This can happen because of kinetic energy, which exists when atoms are hot. It can be influenced by such a thing as pressure. The strong force works at much shorter distance than gravity and magnetism, which is why it can overcome electromagnetism at the close range of nuclei nearly together.
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.
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.
Explain why electrons in metals are both like glue and not like glue?
They are like glue because they 'bind' and hold the metal atoms together in a stabilized structure. They are however unlike glue as the electrons are able to freely move around.
Do noble gases have a ionic bond?
No, noble gases do not combine to form any kind of bond as they have stable electronic configurations.What is an atom?An atom consists of a bunch of electrons, protons and neutrons. The electrons arrange themselves in "electron shells". These electron shells always have a number of 1 to 8 electrons. Except for the first shell, that can only hold 2 electrons.So if an atom has 12 electrons, it will have the following structure:First (inner) shell of 2 electronsA second shell with 8 electronsAnd an outer shell with 2 electronsThe outermost shellThis outer shell electrons, are called the valence electrons. They are the most important since they determine how the atom will behave in chemical reactions but also other features of the atom. Note: That's why in the periodic table atoms are sorted by their amount of electrons. Very interesting is that atoms with the same amount of valence electrons (but different amount of shells) show the same physical characteristics.The atoms who have 8 valence atoms, that's the maximum an atom can have on it's outer shell, are the noble gasses and are chemically the most stable. They all exist in gas form at room temperature, they all show the same physical characteristics like I said before.Binding of atomsWhen atoms bind they share some of their valence electrons with an other atom or by "gaining" or "losing" valence electrons to reach a state with 8 valence electrons. They do this to achieve a more stable state. Covalent bondTwo or more atoms will share their valence electrons together. Because more than one nuclei (center of the atom with the protons and neutrons) are using the same electron those two atoms are being held together by a covalent bond and form a molecule. So if an atom has 2 valence electrons, he will try to bind with an atom which has 6 valence electrons. Or 4 atoms with 2 valence electrons will bind to each other.Ionic bondAn atom with a very low amount of valence electrons will give his valence electrons to an atom with a very high amount of valence electrons and thus making them positively and negatively charged (ion). This inflicted charge will attract the atoms together and they will be held together by an ionic bond. So if an atom has 1 valence electrons, he will try to bind with an atom which has 7 valence electrons.Noble gassesNoble gasses already have 8 valence electrons by themselves so they already have a stable state and don't have to bind with other atoms.
Why are electrons in a metal are both like glue and not like glue?
they are like glue because they bind the metal atoms in a stabilized structure however they are unlike glue because they are free to move around.
Why does nuclear fusion require high temperature?
To bond together, two nuclei must be thrown together with great force. This is because every nucleus has a positive charge and the nuclei repel each other when they come close. If that resistance is overcome and the nuclei actually begin to impact each other, then it is possible for one proton in one nucleus to change to a neutron and bind or 'fuse' together with the other nucleus. The great force required here includes both extreme heat and extreme pressure, comparable to that inside stars.
