If mass of neutron is assumed to half of...

If mass of neutron is assumed to half of its original value. Whereas that of proton is assumed to be twice of its original value, then the atomic mass of `._(6)^(14C` will be:

A

same

B

14.28% more

C

14.28% less

D

28.56% less

Text Solution

Verified by Experts

The correct Answer is:
B

In the isotope `._(6)^(14)C`: number of protons=6
Number of neutrons=8
New atomic mass will be `=2xx6+(1)/(2)xx8=16`
% Increase in mass `=(16-14)/(14)xx100=14.28%`.
