E=mc2. There is potential energy involved in a chemical reaction, or in a nuclear reaction; in both cases, less potential energy means less mass, because of the equivalence of mass and energy. (Note: In chemical reactions, the mass defect is so tiny that it is usually ignored.)
nuclear fusion
It is the mass defect during a fission reaction. Enrgy evolved during a radioactive fission can be calculated using the formula gived by Einstein e =mc
The Energy required o form a nucleus from its parts
The mass defect represents the mass converted to binding energy
m=0.009106u
The calculated mass of the nucleus is always greater than the experimentally determined mass.This difference is variously called as mass defect,mass deficit or mass decrement.The reason for mass defect is that,this deficit mass has been transformed into the nuclear binding energy by Einstein equation E=mc2.
Nuclear binding energy is the energy required to hold the nucleus together. The mass defect is the difference between the mass of a nucleus and the sum of the masses of its individual protons and neutrons. The mass defect is converted into nuclear binding energy according to Einstein's famous equation, E=mc^2, where E is the energy, m is the mass defect, and c is the speed of light.
If you really meant to ask "What is the mass defect of oxygen-16," this is how you do it. mass defect = # of protons x mass of one proton + # of neutrons x mass of one neutron - mass of the nucleus The atomic number of oxygen-16 is 8, so there are 8 protons. The mass of one proton is approximately 1.0073 amu. The Atomic Mass of oxygen-16 is 16, so there are 8 neutrons in oxygen-16. (Atomic mass of 16 minus atomic number of 8 = # of neutrons in oxygen-16.) The mass of one neutron is approximately 1.0087 amu. The mass of the nucleus of oxygen is 16. Now substitute the values into the "mass defect" equation: mass defect = 8x1.0073+8x1.0087-16=approximately 0.128 amu.
If you add the exact mass of the protons, neutrons, and electrons in an atom you do not get the exact atomic mass of the isotope. The diference is called the mass defect. The difference between the mass of the atomic nucleus and the sum of the masses of the particles within the nucleus is known as the mass defect.
The mass defect due to fission or fusion converts to energy according to the equation: E = m c 2
This equation was given by the great scientist Albert Einstein. This is the relation between mass and the energy. According to Einstein, the mass and energy one and the same. This equation is used in the calculation of the energy liberated in the fusion and fission reaction of the nuclei. where the mass is the defect mass or the mass converted into the energy, c is the velocity of light (c= 3x10^8) and E is energy. for example : if in a fission of the U-235 the mass defect is 0.2233 amu , then the energy released will be equals to E= mc2 => E=0.2233x9x10^16 => E= 2.097x10^16 J
nuclear fusion
The principle of the Conservation of mass is so important, as it defines that in physics, nothing can be created or destroyed in an isolated system. It explains that the number of molecules (parts) must be equal on both sides of the equation - A BALANCED EQUATION.
Defect cascading explains how one defect leads to other defects. For Example, employee application salary calculations are not correct when totaling Basic, Tax and Gross, so for this issue defect raised. In this case other modules will block and also same defect will exists in all those modules due to this defect. This is called Defect Cascading.
