Calculate the mass defect of the helium nucleus 42he. the mass of neutral 42he is given by mhe=4.002603u.

The mass defect of the helium nucleus ⁴He₂ is 0.030377 u

Mass defect means the difference between the mass of particles forming an atom with an atomic mass.

Δm = mass defect ( u )

mp = mass of proton ( u )

me = mass of electron ( u )

mn = mass of neutron ( u )

M = atomic mass ( u )

A = mass number

Z = atomic number

Let us now tackle the problem !

Given :
