An atom contains electrons, protons and ...

An atom contains electrons, protons and neutrons. If the mass of each neutrons is halved, and each electron is doubled, then the atomic mass of `._(12)Mg^(24)`

A

Gets doubled

B

Approximately remain same

C

Approximately get reduced by 5%

D

Approximately get reduced by 25%

Text Solution

Verified by Experts

The correct Answer is:
D
`{:(,p,n,"mass"),("initial",12,12,24),("Final",12,6,18):}`
`=(6 xx 100)/(24) = 25%` reduced.
