    Alpha Particle shot at Nucleus Energy

    Thanks, I think I figured it out upon further inspection of the text. rd, distance of closest approach, may be calculated as follows: rd = kqQ/.5mv2

    Alpha Particle shot at Nucleus Energy

    Homework Statement What energy alpha particle would be needed to just reach the surface of an Al nucleus if its radius is 4fm? *This problem is found in a section dealing with Rutherford's gold foil scattering experiment, so take it in that context. Homework Equations F=(kqQ)/r2 The Attempt...

    Revising Activity Series for Elements: A Personal Endeavor

    PERFECT. Thank you much for the very informative response. This is exactly the type of answer I was looking for, and it all makes sense now. I was just getting frustrated... not a single teacher or professor I have spoken to was able to explain it or even understood it themselves.

    Revising Activity Series for Elements: A Personal Endeavor

    Electronegativity in kJ mol^-1 would be amazing. I just need some sort of real value like that. Thanks much for naming a few other scales for me. That should prove to help me. I haven't been able to find out if they use any type of unit I could use, but with more research, I'm sure I will...

    Revising Activity Series for Elements: A Personal Endeavor

    All right, before reading this, please understand that I am only in my second year of study in high school. Bear with me... When looking at the activity series or metals and comparing it to the electronegativity and ionization energies of the elements, I noticed something quite interesting...

    Can Coarse Aluminum Flake be Used in a Thermite Reaction?

    I have a batch of each method reacting right now. The bleach is super-fast... didn't realize that. The other is a lot of work, actually. Looks like it's working though. I have a nice precipitate forming, but it took forever to complete the first step of reacting one pad of steel wool in HCl...

    Can Coarse Aluminum Flake be Used in a Thermite Reaction?

    Your thorough examination of thermite that has been brought up numerous times makes me apt to come to you for some discussion/answers. I've seen all the mentioned iron oxide making processes, but I have yet another I'd like checked and thought through. What if I did the following... acid...
