The basic answer is that nuclear fusion can only occur at VERY high temperatures like MILLIONS of degrees.
You can relate it to the sun where the sun is around 10mil degrees and bonds hydrogen atoms to form helium.

∙ 13y agoIn a tokamak on Earth, the plasma of deuterium and tritium mixture is heated to several hundred million degC. In the sun the fusion reaction is rather different because of the intensely high pressure (due to gravity) at the sun's centre, and such high temperatures are not necessary to start fusion.

Is it a fission or fusion reaction?
Fission and fusion are different nuclear reactions.
How to make a model of fusion reaction?
There is a nice illustration of solar fusion at the link given below
What process occurs in a controlled fusion reaction?
In a controlled fusion reaction, a process of nuclear fusion occurs, but it is controlled, so that it does not grow uncontrollably, to become, for example, a thermonuclear bomb. Note: This has not been accomplished yet.
Is fusion an atomic process that is used to produce energy?
Fusion occurs when two atomic nuclei collide. The reaction that is produce by the collision can be used to provide energy. Fusion is the reaction that powers most active stars in the universe.
What reaction in the sun produces energy?
nucleur fusion
Is fusion a chemical?
No, fusion is a type of nuclear reaction.
A reaction in combining smaller atomic nuclei is?
nuclear fusion
What happens when a fusion reaction is uncontrolled?
fusion bomb explosion
Is fusion chemical nuclear or mechanical?
Fusion is a nuclear reaction.
Is fusion a type of chemical reaction?
False
Is nuclear chain reaction is called fusion?
The idea of nuclear fusion occurring at room temperature is called cold fusion.
What is true about the balance of mass in a fusion reaction?
In a fusion reaction the mass of the products is less than the mass of the reactants.
What chemical reaction fuels the sun?
Fusion is the type of nuclear reaction that fuels your solar system.
Is it a fission or fusion reaction?
Fission and fusion are different nuclear reactions.
Describe what takes place in a nuclear fusion reaction?
In nuclear fusion reaction two nuclei are combined by providing the energy.
Is the sun a hot fusion or cold fusion?
Yes
What does fusion have to do with the sun?
Nuclear reaction
