Q: What is the minimum amount of energy necessary to remove a proton from the nucleus of a 42-Ca atom, thereby converting it into a 41-K atom? The former has a mass of 41.958618 u, the latter 40.961825 u, and the hydrogen atom has a mass of 1.007825 u.
My answer:
42-Ca --> 41-K + 1-H
Therefore change in mass (Delta m) = 0.011032 u
I then used this mass in E = mc^2
and got the answe E = 10.278 MeV
Can someone else try this question and see if they get the same answer? Or tell me if i have done it correctly/incorrectly
Thanks in advance
