## kym02 one year ago why is it easier to 'hit' a nucleus with a neutron than with a proton?

1. theEric

I really don't know. But if I had to guess, I'd think about the charge. What do you think?

2. theEric

Think about the nucleus, the neutron, and proton.

3. kym02

I was thinking the same thing...ehh i dont know :l

4. theEric

Well, copy and paste this, and list their charges: Neutron: Proton: Nucleus:

5. kym02

Neutron: neutral Proton: +1 Nucleus: +1

6. theEric

Right! And that's good enough. Really, the nucleus will have a +1 charge for each proton, so the total charge is +1$$\times$$ the number of protons. So, you know the like charges repel, right?

7. kym02

yep

8. theEric

Right! So, you have this.|dw:1398301781038:dw| Which will be easier to move, and why?

9. theEric

If you need a hint, think about the repelling. That electrostatic force.

10. kym02

oh so since the protons and nucleus are positively charged, repulsion will thus occur making it difficult to hit the nucleus. And since the neutron is neutral, it won't have any effect. Infact, it would actually be attracted to the nucleus. Am I right?

11. kym02

oh wait, scratch that attracted part 'cause opposite attracts.

12. theEric

With your edit, you're completely correct! :) I think you covered it all!

13. kym02

That was quite simple :)

14. theEric

After you broke it down, yep! :)

That's what a lot of problems take. They're complex when you think of everything together. But it's easier when you understand it, which sometimes breaking down pieces so you can understand them and put the pieces back together. Then the problem will be easier.

17. kym02

hmm yeah indeed!
