What correctly explains why the actual mass of an atom is less than the calculated mass of its protons neutrons and electrons?

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.


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.


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.


How is mass and volume determined in density?

Mass and volume are not determined by density. Rather density is determined by mass and volume


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 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.


What does mass defect represent?

The Energy required o form a nucleus from its parts


Why is the krypton atomic mass not determined?

The relative atomic mass is 83.798. So where did you get that it is not determined.


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 Emc2 have to do with mass defect?

It allows you to calculate the corresponding energy.


What is the mass of oxygen 16?

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.
