Atoms consist of electrons, protons and neutrons. If the mass attributed to neutron was halved and that attributed to the electrons was doubled, the atomic mass of

{\mathrm{\;}_6}{\mathrm{C}^{12}}

would be approximately:

View answer and explanation

Correct option: D

Reduced by 25%

Option D (Reduced by 25%) is correct because halving the neutron mass reduces the total atomic mass from 12 to 9, which is a 25% reduction.
