What is the fusion reaction in the Sun?

In the core of the Sun hydrogen is being converted into helium. This is called nuclear fusion. It takes four hydrogen atoms to fuse into each helium atom. During the process some of the mass is converted into energy.

What are the steps to fusion in the Sun?

Here are the steps.

  • Two pairs of protons fuse, forming two deuterons.
  • Each deuteron fuses with an additional proton to form helium-3.
  • Two helium-3 nuclei fuse to create beryllium-6, but this is unstable and disintegrates into two protons and a helium-4.

How many fusion reactions occur in the Sun?

If the Sun gives off 4 x 1026 watts of energy, how many fusion reactions happen every second? 4 x 1026 Joules/second / 4.3 x 10-12 Joules/react = 9.3 x 1037 reactions/second. Question 4: 2 x 1030 kg / 6.224 x 1011 kg/s 3.213 x 1018 seconds = 1011 years!

What are the three steps of nuclear fusion in the Sun?

The steps are:

  • Two protons within the Sun fuse.
  • A third proton collides with the formed deuterium.
  • Two helium-3 nuclei collide, creating a helium-4 nucleus plus two extra protons that escape as two hydrogen.

What causes fusion?

To make fusion happen, the atoms of hydrogen must be heated to very high temperatures (100 million degrees) so they are ionized (forming a plasma) and have sufficient energy to fuse, and then be held together i.e. confined, long enough for fusion to occur.

What type of reaction takes place in Sun?

nuclear fusion reaction
A nuclear reaction combining nuclei of lighter atoms together to form heavier nuclei resulting in the release of tremendous amount of energy is called a nuclear fusion reaction. Nuclear fusion reaction takes place in the sun.

What type of reaction takes place in sun?

How does fusion power work?

Fusion power is a proposed form of power generation that would generate electricity by using heat from nuclear fusion reactions. In a fusion process, two lighter atomic nuclei combine to form a heavier nucleus, while releasing energy. Devices designed to harness this energy are known as fusion reactors.

Which two elements are involved in the Sun’s fusion reaction?

1 Answer. hydrogen atoms fusing to Helium atoms and some energy is released.in Sun.

What type of reactions occur in the Sun?

In the Sun, the nuclear reaction which occurs is called the proton-proton cycle, in which four Hydrogen atoms are combined in a series of reactions to form one Helium atom; this chain of reactions also produces energy (in the form of gamma rays) and some other particles called neutrinos.
