PHYIC CALCULATOR
Mass Defect Calculator
A precise tool.
What is the Mass Defect Calculator & How does it work?
The mass defect, denoted as (Delta m), is the difference between the sum of the masses of the free constituent protons and neutrons that make up an atomic nucleus and the actual mass of the nucleus itself. This discrepancy arises due to the binding energy that holds the nucleus together.
(Delta m = (A cdot m_p + Z cdot m_n) – M_{nucleus})
A = Mass number, Z = Atomic number, m_p = Mass of proton, m_n = Mass of neutron, M_{nucleus} = Nuclear mass
The binding energy can be calculated using Einstein’s equation (E=mc^2), where (E) is the binding energy and (c) is the speed of light.

Frequently Asked Questions
What is mass defect in physics?
Mass defect is the difference between the sum of the masses of free constituent protons and neutrons that make up an atomic nucleus and the actual mass of the nucleus itself.
How do I calculate binding energy from mass defect?
Binding energy can be calculated using Einstein’s equation E=mcΒ², where E is the binding energy, m is the mass defect, and c is the speed of light.
What causes the discrepancy in mass between free nucleons and the nucleus?
The discrepancy arises due to the binding energy that holds the nucleus together, which reduces the total mass when compared to the sum of free protons and neutrons.
Can you explain the formula for mass defect?
The formula for mass defect is Ξm = (A Β· mp + Z Β· mn) – Mnucleus, where A is the mass number, Z is the atomic number, mp is the mass of a proton, mn is the mass of a neutron, and Mnucleus is the nuclear mass.
How does mass defect relate to nuclear stability?
Mass defect is related to nuclear stability; nuclei with lower mass defects are more stable because they have less energy binding them together.
What units are typically used for mass defect and binding energy?
Mass defect is usually measured in atomic mass units (u) or kilograms, while binding energy is typically measured in joules or megaelectron volts (MeV).
