Why is high pressure required to cause atomic nuclei to crash into one another in stars?
Extremely high pressure is required to initiate fusion in the stars. This pressure overcomes the normal repulsion between protons, allowing protons of hydrogen to get close enough for the strong atomic force to take over and change the force to an attractive force, forming helium.
Not stated, but answered for completeness sake... Extremely high temperature is also required in order to strip the hydrogen nuclei of their electrons, forming an ionized plasma, in order to get past the additional repulsion that the electron cloud would represent.

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.
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 is the binding energy of iron and how does it impact the stability of atomic nuclei?
The binding energy of iron is the energy required to hold its nucleus together. Iron has a high binding energy, making its nucleus stable. This stability is important for the overall stability of atomic nuclei in general.
Why does the plasma in a fusion reactor need to be very hot?
The plasma in a fusion reactor needs to be very hot to achieve the high temperature and pressure conditions required to overcome the electrostatic repulsion between positively charged atomic nuclei and initiate the fusion reaction. This high temperature allows the atomic nuclei to collide with enough energy to overcome the electrostatic barrier and fuse together, releasing energy in the process.
What type of nuclear reaction releases energy through the combination of atomic nuclei, unlike fission reactions which involve the splitting of atomic nuclei?
The type of nuclear reaction that releases energy through the combination of atomic nuclei is called fusion. This is different from fission reactions, which involve the splitting of atomic nuclei.
Is atomic nuclei required in a chemical reaction?
No, atomic nuclei is not required for a chemical reaction.

What is nuclei known as?
When the atomic number of one nucleus is the same with the mass number of another nucleus and the mass number the same with the atomic number of the second nucleus, then these two nuclei are called mirror.
What is known as mirror nuclei?
When the atomic number of one nucleus is the same with the mass number of another nucleus and the mass number the same with the atomic number of the second nucleus, then these two nuclei are called mirror.
