Mass defect of hydrogen atom

In summary, the mass defect of a hydrogen atom is the difference between its mass and the combined masses of its constituent particles. It can be calculated using Einstein's famous equation and is important in understanding nuclear binding energy and reactions. In nuclear fusion, the conversion of mass into energy results in a mass defect. The mass defect of a hydrogen atom is relatively small compared to other elements, but increases as the number of particles in an atom increases.

What's the mass difference between a hydrogen atom and it's constituent particles when they are free, I'm talking about the proton and the electron, not the quarks that make up the proton.

The binding energy (13.7 eV) divided by c^2.

Related to Mass defect of hydrogen atom

1. What is the mass defect of a hydrogen atom?

The mass defect of a hydrogen atom is the difference between the mass of a hydrogen atom and the combined masses of its constituent particles (proton and electron). This difference is caused by the conversion of some mass into energy during the formation of the atom.

2. How is the mass defect of a hydrogen atom calculated?

The mass defect of a hydrogen atom can be calculated using Einstein's famous equation E=mc², where E is the energy released during the formation of the atom, m is the mass defect, and c is the speed of light.

3. Why is the mass defect of a hydrogen atom important?

The mass defect of a hydrogen atom is important because it provides evidence for the existence of nuclear binding energy, which is the energy that holds the nucleus of an atom together. It also plays a crucial role in understanding the stability and energy release of nuclear reactions.

4. What is the relationship between mass defect and nuclear fusion?

Mass defect is a fundamental concept in nuclear fusion, which is the process of combining two or more atomic nuclei to form a heavier nucleus. During this process, some of the mass of the combined nuclei is converted into energy, resulting in a mass defect.

5. How does the mass defect of a hydrogen atom differ from that of other elements?

The mass defect of a hydrogen atom is relatively small compared to other elements, as it contains only one proton and one electron. The mass defect increases as the number of protons and neutrons in an atom increases, reaching its maximum in the heaviest elements. This is due to the increasing nuclear binding energy needed to hold together larger and more complex nuclei.
