# What is the formula for nuclear fusion?

## What is the formula for nuclear fusion?

The formula is B = (Zmp + Nmn − M)c2, where mp and mn are the proton and neutron masses and c is the speed of light.

### How do you calculate nuclear fission?

In the first step, a uranium-235 atom absorbs a neutron, and splits into two new atoms (fission fragments), releasing three new neutrons and a large amount of binding energy. In the second step, one of those neutrons is absorbed by an atom of uranium-238, and does not continue the reaction.

#### What is the difference between a fission and fusion equation?

Simply put, fission is the division of one atom into two, and fusion is the combination of two lighter atoms into a larger one. This splits the target nucleus and breaks it down into two smaller isotopes (the fission products), three high-speed neutrons, and a large amount of energy.

What are the 3 steps of nuclear fusion?

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.

Is the sun fission or fusion?

Although the energy produced by fission is comparable to what is produced by fusion, the core of the sun is dominated by hydrogen and at temperatures where hydrogen fusion is possible, so that the dominant source of energy per cubic meter is in fusion rather then the fission of very low abundance radioisotopes.

## Is nuclear energy fission or fusion?

The foundation of nuclear energy is harnessing the power of atoms by splitting apart, a process called fission, or combining them, called fusion. This splits the target nucleus and breaks it down into two smaller isotopes (the fission products), three high-speed neutrons, and a large amount of energy.

### Is fission more powerful than fusion?

Fusion only produces more energy than it consumes in small nuclei (in stars, Hydrogen & its isotopes fusing into Helium). The energy per event is greater (in these examples) in fission, but the energy per nucleon (fusion = about 7 MeV/nucleon, fission = about 1 Mev/nucleon) is much greater in fusion.

#### Does fission or fusion produce more energy?

Fission is when a large nucleus divides into smaller nuclei releasing energy. Certain elements such as Uranium-235 can be made to fission easily. So, the answer is fusion produces more energy if it involves light elements and fission produces more energy if it involves heavy elements.

What is the difference between nuclear fission and nuclear fusion?

Nuclear fission and fusion involve the disintegration and combination of the elemental nucleus. In the case of nuclear fission, an atom divides into two or more smaller or lighter atoms. Nuclear fusion occurs when two or more atoms join or fuse together to form a large or heavy atom.

How to calculate the energy released during fission and fusion?

To calculate the energy released during mass destruction in both nuclear fission and fusion, we use Einstein’s equation that equates energy and mass: E is energy (Joules). Calculate the amount of energy (in electronvolts per atom and kilojoules per mole) released when the neutron-induced fission of 235 U produces 144 Cs, 90 Rb, and two neutrons:

## How are radioactive particles produced in nuclear fusion?

Fusion occurs in stars, such as the sun. Fission produces many highly radioactive particles. Few radioactive particles are produced by fusion reaction, but if a fission “trigger” is used, radioactive particles will result from that. Critical mass of the substance and high-speed neutrons are required.

### What kind of fission is needed to make a hydrogen bomb?

For example, the so-called hydrogen bomb (or H bomb) is actually a deuterium–tritium bomb (a D–T bomb), which uses a nuclear fission reaction to create the very high temperatures needed to initiate fusion of solid lithium deuteride ( 6LiD), which releases neutrons that then react with 6Li, producing tritium.
