Because atoms have negatively charged electrons orbiting the outside of them, atoms will repel each other. This means that it is extremely rare for atoms to collide, but when they do, the reaction depends on why it happened. If they are in a star for example, and the huge gravity and heat of the star forces them together, any atom lighter than iron will undergo fusion and make a heavier element. In fission reactors, it is extremely rare for an atom to hit another atom, but it can happen. Most of the time they will simply be hit by a flying electron before they can fuse, but even if they weren't, the atoms used in a fission reactor are much much heavier than iron and will not undergo fusion. The reason iron and anything heavier than iron cannot undergo fusion is that iron will absorb a huge amount of energy before it will fuse. In stars, the most powerful stable fusion reactors we know of, the iron will actually absorb so much energy that it kills the star. This is why stars will collapse after a short amount of time as a supernova. The supernova has layers with heavier and heavier atoms. When it reaches a layer with iron, it suddenly loses large amounts of energy and loses the ability to counteract gravity. This causes it to collapse into a dwarf star, or explode.
What else can I help you with?
What direction the thermal energy flows?
it's from hotter one to the cooler one,because when electron of the body from which it is flowing gets energy and gets excited and goes to its extrime position and they gets colides with another atom and transfers some energy to it . and the 2nd atom to the third atom and so on and the energy gets transmited.
What happens to the momentum of one object when it colides with another object if they are travelling in the same dirction?
Some momentum is transferred from one to the other.
What happens when an oceanic crust colides with another oceanic crust?
The younger of the two plates, because it is less dense,* will ride over the edge of the older plate.
When do elephants have 8 feet?
elephant have 8 feet when another elephant colides. no one noes how they colide but they just do. so that's why elephants may have eight feet.
Can an atom burn another atom?
no

What is the ability to attract electrons from another atom called?
electronegativity
What distinguishes one atom from another atom?
The number of protons in the nucleus of an atom distinguishes it from another atom. This number is known as the atomic number and determines the element to which the atom belongs.
What determines how an atom behaves when it encounters another atom?
The electron configuration of an atom determines how it behaves when it comes into contact with another atom.
What processes forms an island?
When subduction also occurs where the edge of a continental plate colides with an onceanis plate
What part of an atom is used to tell how one atom will bond with another atom?
Electron
What happens to a radioactive atom after it has emitted its radiation?
The initial atom is transformed in another atom.
