Homework Equations

The Attempt at a Solution

i say that the mass decrease. but i don't know why, can someone please explain it to me

i say that the mass decrease. but i don't know why,

Then you can't really say that then can you?

What positive and negative charged particles are there in an atom, which ones can be easily added/removed. To get a positive charge would you have to add or remove particles?

 

[unseenoi]

You would have to Add particles.

 

[mgb_phys]

No.

It's a poorly-worded question because, in fact, the answer can be either increase OR decrease, but since I think adding hydrogen nucleii is probably not what the question is asking about, I think post #2 has the intent of the question correct.
