## kym02 Group Title why is it easier to 'hit' a nucleus with a neutron than with a proton? 2 months ago 2 months ago

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

2. theEric Group Title

Think about the nucleus, the neutron, and proton.

3. kym02 Group Title

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

4. theEric Group Title

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

5. kym02 Group Title

Neutron: neutral Proton: +1 Nucleus: +1

6. theEric Group Title

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 Group Title

yep

8. theEric Group Title

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

9. theEric Group Title

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

10. kym02 Group Title

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 Group Title

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

12. theEric Group Title

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

13. kym02 Group Title

That was quite simple :)

14. theEric Group Title

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.

hmm yeah indeed!
