Definig 1 amu as 1//12 of the mass of a ...

Definig 1 amu as `1//12` of the mass of a `._(6)^(12)C` atom means that protons and neutrons each have a mass of almost exactly 1 amu, because

A

atin as a whole is electrically neutral

B

`C` atom contains equal number of protons and neutrons

C

the mass of an electron is negligibel compared with the mass of proton and neutron

D

neutrons are slightly heavier than protons

Text Solution

Verified by Experts

The correct Answer is:
C
`m_(p) = 1.007276, m_(n) = 1.008665, m_(e) = 5.485799xx10^(-4)`
