Which conditions are required to form 4 2he during the fusion reaction in the sun?
High Temp and high pressure
What two things are necessary for fusion reaction to take place in a star?
Fusion will ignite when the temperature and pressure are high enough.
What causes radioactive explosions?
An uncontrolled neutron chain reaction in a supercritical mass of fissile material.Very high temperature and pressure, enough to ignite thermonuclear fusion in fusion fuel.
How hot does a fusion reaction have to be?
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.
Why is it more difficult to start a fusion reaction than fission?
Fission reactions start naturally if the proportion of U-235 is high enough; there is evidence this has happened in places in Africa in the distant past of Earth's history. Fusion reactions require more heat and pressure than we really know how to provide so as to keep a reaction going.

Fusion will ignite when the temperature and pressure are high enough.
Why is the sun's energy generated mostly at its center and not near its surface?
At the center, both the temperature and the pressure are highest. Both a high pressure and a high temperature increase the likelihood of fusion.
What causes radioactive explosions?
An uncontrolled neutron chain reaction in a supercritical mass of fissile material.Very high temperature and pressure, enough to ignite thermonuclear fusion in fusion fuel.
Why are fusion reactions difficult to recreate in a scientific laboratory?
Because of the very very high temperature and pressure required to get them started.
What is the major problem with fusion reactions as an energy source?
Problem on nuclear fusion is upon confinement of reaction in earth atmosphere. Nuclear fusion required very high temperature to initiate the reaction. Sustaining reaction is not easy. It is likely the earliest nuclear fusion will be available commercially by 2050. It is a little far future for the current energy crisis would reach it peak around 2040.

Nuclear fusion can only occur in areas of?
In areas of high temperature and high pressure
Does nuclear fusion occur in stars?
Nuclear fusion takes place only in the core of the Sun, or any star. Extremely high energy (temperatures) are required to force atomic nuclei together. The fusion reaction releases heat energy, which continues the fusion of other nuclei.
What is fusion ignition?
Fusion ignition refers to the manner in which a fusion reaction is "ignited" to make it happen. In nature stars, which are huge fusion reactors, using their enormous pressure to compress and heat matter (mostly hydrogen) when they are first formed. This massive heating and pressure "triggers" or "ignites" the fusion chain reaction. The chain will then be sustained by the heat given off during the fusion process, with massive gravity keeping the whole thing "under control" or "in one place" so it will continue. During this process the hydrogen is pushed/compressed together so far that it goes past the repulsive nuclear forces (which produces the nuclear fusion energy) and is then converted into the element known as helium. This refers to reaching the very high temperature required to achieve nuclear fusion. It could be in a tokamak type reactor such as JET, or the laser being built in California
Nuclear fusion powers the sun what elements are fused together in the sun?
It is just protons joining together, which are hydrogen ions, so the only fuel required is hydrogen, the reaction proceeds due to the high pressure at the sun's core, due to the immense gravitational compression. See the link below
Is it possible for fusion reaction to be happening at a planets core?
No. Fusion requires high concentrations of Hydrogen. Planets are made from substantially heavier elements. Additionally, a planet massive enough to begin a fusion reaction literally becomes a star.
