Mass Defect & Binding Energy (6 of 7), Nuclear Fusion

preview_player
Показать описание
Using the average atomic mass this video explains how to determine the mass defect and amount of energy released from the fusion of deuterium and tritium to produce helium-4.

The mass of an atomic nucleus is less than the sum of the individual masses of the free constituent protons and neutrons, according to Einstein's equation E = mc2. Nuclear binding energy is the minimum energy that would be required to disassemble the nucleus of an atom into its component parts. These component parts are neutrons and protons, which are collectively called nucleons. The binding energy is always a positive number, as we need to spend energy in moving these nucleons, attracted to each other by the strong nuclear force, away from each other. This 'missing mass' is known as the mass defect, and represents the energy that was released when the nucleus was formed.

The whole time I was thinking how does increase in binding energy leads to energy release...u Sir, saved me from a sleepless night 😃

Thank you very much Sir. This appeared in my past question and I've been struggling with it until I came across this video

I thought this was going to be a video about physics, but it is just a video about unit conversion 😢

from what I've seen in your videos and other I am assuming that when we see an electron on one side of the equation for example in electron capture we dont consider it not the equation for the mass defect. and we assume that even for this that it is negligible.

How can I know the masses of the reactants and the products? And is it energy released or absorbed?

I don't understand where is mass deficit ?
LHS - 2 proton 3 neutron
RHS - 2 proton 3 neutron
Please make me understand, I can't sleep without getting answer .

I got a question, fission reaction is releasing more energy than fussion reaction ?

I guess I am the first to comment, do I get a prize?
Please I want some cold fusion.
