For an atom...

( proton mass * number of protons + neutron mass * number of neutrons + electron mass * number of electrons ) - mass of atom in neutral state = mass deficit

How is nuclear binding energy related to the mass defect?

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.


What is the binding energy of a nucleus that has a mass defect of 5.81x10-29?

The mass defect represents the mass converted to binding energy


What does mass defect represent?

What is the mass defect?

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.


What is mass defect associated with?

nuclear fusion


Why is mass defect important?

E = MC2; energy is equal to a quantity of matter. When protons (and neutrons) combine in an atomic nucleus, the resultant mass is less than that of the individual particles. This is the mass defect, and the 'missing' mass is a result of the energy binding the particles together. The larger the mass defect for a particular atom (isotope), the larger the amount of nuclear binding energy.


What are the units in measurement for mass?

Mass units in the Metric system: Gram, kilogram Mass units in the English system: Poundal, Slug


What is the binding energy of a mole nuclei with a mass defect of 0.00084?

The binding energy is the mass defect, times the square of the speed of light.The amount stated seems to be an awfully high mass defect, though.


2 units of mass?

There are several different units of mass used. Grams, kilograms, and milligrams are all different SI units of mass.


How is the mass defect determined?

The mass of a nucleus is subtracted from the sum of the masses of its individual components.
