# Characteristics of nuclear fusion

## What are the characteristics of nuclear fusion reaction?

**two or more light nuclei collide to form a heavier nucleus**. The nuclear fusion process occurs in elements that have a low atomic number, such as hydrogen. Nuclear Fusion is the opposite of nuclear fission reaction, in which heavy elements diffuse and form lighter elements.

## Which is a characteristic of nuclear fission?

## Which is a characteristic of nuclear fusion but not nuclear fission?

**A Tremendous Amount of Energy**:

Nuclear fusion is the fusion of two or more lighter atoms into one that is larger. Nuclear fusion releases a tremendous amount of energy; in fact, three to four times as much energy as a nuclear fission reaction.

## Which best describes nuclear fusion?

**Nuclei combine to form a heavier nucleus, releasing energy**.

## What is nuclear fusion with example?

**when two light atomic nuclei join together to form a single, heavier nuclei**. This process occurs naturally inside stars, including the Sun, and releases large amounts of energy.

## What are 3 differences between fission and fusion?

…

Nuclear Fission vs Nuclear Fusion.

Nuclear Fission | Nuclear Fusion |
---|---|

Little energy is needed to split an atom in a fission reaction | High energy is needed to bring fuse two or more atoms together in a fusion reaction |

## Which statement is true about nuclear fusion?

In the sun, two unstable hydrogen atoms combine and form a helium atom that is heavier than the hydrogen atoms and generates atomic energy, which powers the sun. Therefore, the true statement about nuclear fusion is (d) **It produces nearly all the elements that are heavier than helium**.

## What are the conditions necessary for nuclear fusion?

**a temperature of at least 100 million degrees Celsius**. The ions have to be confined together in close proximity to allow them to fuse.

## Which is an example of fission reaction?

**splitting of the uranium-235 nucleus when it is bombarded with neutrons**. Various products can be formed from this nuclear reaction, as described in the equations below. Another important example of nuclear fission is the splitting of the plutonium-239 nucleus.

## Which is a characteristic of nuclear fusion produces radioactive waste?

**no radioactive waste**, and the fuel is plentiful.

## Which feature of nuclear fission reactions allows these reactions?

**Neutrons start the reaction and are released during it**.

## Is fission a nuclear reaction?

**Both fission and fusion are nuclear reactions**that produce energy, but the processes are very different. Fission is the splitting of a heavy, unstable nucleus into two lighter nuclei, and fusion is the process where two light nuclei combine together releasing vast amounts of energy.

## What are the types of nuclear fusion?

**those that preserve the number of protons and neutrons and (2) those that involve a conversion between protons and neutrons**.

## Which statement about nuclear fusion is true?

In the sun, two unstable hydrogen atoms combine and form a helium atom that is heavier than the hydrogen atoms and generates atomic energy, which powers the sun. Therefore, the true statement about nuclear fusion is (d) **It produces nearly all the elements that are heavier than helium**.

## What are products of nuclear fusion?

**helium, which is an inert gas**. It also produces and consumes tritium within the plant in a closed circuit. Tritium is radioactive (a beta emitter) but its half life is short. It is only used in low amounts so, unlike long-lived radioactive nuclei, it cannot produce any serious danger.

## What are the advantages of nuclear fusion?

**Advantages of fusion power**

- No carbon emissions. The only by-products of fusion reactions are small amounts of helium, an inert gas which can be safely released without harming the environment.
- Abundant fuels. …
- Energy efficiency.

## What causes nuclear fusion?

**two light atoms bond together, or fuse, to make a heavier one**. The total mass of the new atom is less than that of the two that formed it; the “missing” mass is given off as energy, as described by Albert Einstein’s famous E=mc2 equation.

## What is nuclear fusion simple?

## What are 3 disadvantages of nuclear fusion?

**What are the Disadvantages of Nuclear Fusion?**

- The difficulty for Achieving the Fusion Power.
- Radioactive Wastes.
- Need More Investigation and Brainpower is Required in order to Solve its Problems.
- Its practical energy results are still considerably unreachable.
