Question 603: Atoms & Nuclei

Question

M
n
and M
p
represent the mass of neutron and proton respectively. An element having mass M has N neutrons and Z protons, then the correct relation will be

Accepted Answer

Given : Mass of neutron = M
n
Mass of proton = M
p
;
Atomic mass of the
element = M ;
Number of neutrons in the element
= N and number of protons in the element = Z.
We know that the atomic mass (M) of any stable
nucleus is always less than the sum of the masses
of the constituent particles.
Therefore, M $$<$$ [NM
n
+ ZM
p
].
X is a neutrino, when b-particle is emitted.

Answer

M < {N $$ \cdot $$ M
n
+ Z $$ \cdot $$ M
p
}

Answer

M > {N $$ \cdot $$ M
n
+ Z $$ \cdot $$ M
p
}

Answer

M = {N $$ \cdot $$ M
n
+ Z $$ \cdot $$ M
p
}

Answer

M = N {M
n
+ M
p
}
