What is plasma the ionized gas?
Plasma is a gas where the "temperature" is so high that all the electrons have been removed from the atoms, leaving just the positively charged nuclei and free electrons. There can be no molecules in a plasma as without electrons the bare atomic nuclei repel each other.
Why do 2 nuclei repel each other?
Two nuclei repel each other due to the electrostatic force between their positive charges. Like charges repel each other according to Coulomb's law, causing the nuclei to push away from each other.
What keeps atoms from fusing together?
It is the nulei which fuse. Nuclei are positively charged and thus repel each other. The kinetic energy of the nuclei must be very large for nuclei to be able to fuse, such as at the surface of the sun, where hydrogen nuclei fuse to form helium nuclei.
Why dont charged nuclei repel each other in a plasma?
They do. In those plasmas which don't fly apart there are other factors. In plasmas for fusion power, the plasmas are constrained by magnetic forces which keep the material in proximity. There is also the strong nuclear force. This is a very strong force, with a very short range. If two positively charged nuclei can be forced close enough together, then the strong nuclear force, which pulls them together, will become more powerful than the electromagnetic force, which pushes them apart. Then they form one nucleus, and spit out a lot of energy, and sometimes a neutron.
What does a positive charged object repel?
A positively charged object will repel other positively charged objects. Additionally, it will attract negatively charged objects.
Why did nuclei fuse together?
Basically because both nuclei are positively charged so repel each other.

Why do protons in an atom not separate?
Being positively charged, particles protons should repel each other but they are held together in the nuclei of atoms.

Why does nuclear fusion bring nuclei extremely close together?
Because the nuclei are all positively charged they repel each other. They are made to stick to each other when brought close enough for the strong force to take hold.
Why does nuclear fusion require bringing nuclei extremely close together?
Because the nuclei are all positively charged they repel each other. They are made to stick to each other when brought close enough for the strong force to take hold.

A positively charged object will repel other positively charged objects. Additionally, it will attract negatively charged objects.
What is the force that usually stops two nuclei getting close together?
The electromagnetic force is the force that typically prevents two nuclei from getting too close together. This force arises from the interaction of positively charged protons in the nuclei, causing them to repel each other.
Why is extremely high pressure required to cause atomic nuclei to crash into one another stars?
Extremely high pressure is required in stars to cause atomic nuclei to crash into one another because the nuclei have positive charges, which repel each other due to the electromagnetic force. The high pressure overcomes this repulsion, allowing the nuclei to come close enough for the strong nuclear force to take effect, resulting in nuclear fusion and the release of energy.
What do like charged ions do?
Like-charged ions repel each other. Opposite-charged ions attract each other.
