Chemistry Question on Structure of atom
Mn and Mp represet the mass of neutron and proton respectively. An element having mass M has N neutron and Z-protons, then the correct relation will be
A
M < {N.Mn + Z.Mp}M < {N.Mn + Z.Mp}
B
M > {N.Mn + Z.Mp}
C
M = {N.Mn+Z.Mp}
D
M=N{Mn + Mp}
Answer
M < {N.Mn + Z.Mp}M < {N.Mn + Z.Mp}
Explanation
Solution
The correct option is(A): M < {N.Mn + Z.Mp}.
The mass of a neutron is denoted as Mn, and the mass of a proton is denoted as Mp. It's a well-established fact that the atomic mass (M) of any stable nucleus is consistently lower than the combined masses of its constituent particles:
M < {N.Mn + Z.Mp}
Here, N represents the number of neutrons, Z represents the number of protons, and Mn and Mp are the masses of neutrons and protons, respectively.
