    Taking Apart an Alpha Particle

    Oh okay I think I understand. So if I were to do the steps for removing the first neutron, would I subtract 1 electron from 3H and then add 1 neutron to 2H?

    Taking Apart an Alpha Particle

    I got the right answer for removing the first neutron using this method. Is this the right way to solve the problem? Maybe the problem is glitched. There was a crash in the system before the course started so there's still lots of glitches.

    What is the activity of 99Tc in a pharmaceutical after 1.5 hours?

    Nevermind. I ended up figuring out my mistake.

    Taking Apart an Alpha Particle

    For some reason the correct answer was 19.8 Mev, but that doesn't make sense to me. >_<

    Taking Apart an Alpha Particle

    Homework Statement An alpha (α) particle is the nucleus of a 4He atom and consists of 2 neutrons and two protons bound together. Let's take apart an α particle, step by step, looking at the energy required at each step. To do so, we may want to use the following atomic masses: 4He: 4.0026 u...

    What is the activity of 99Tc in a pharmaceutical after 1.5 hours?

    Homework Statement *I'm only stuck on part c During the testing process for some pharmaceuticals, the drug is "tagged" with a radioactive material. This way researchers can determine if the pharmaceutical is going to other parts of the body than the intended target and what effect it has on...

    Solve De Broglie Waves Homework

    Homework Statement Atoms are on the order of one Angstrom (A) or 10-10m in size while the diameter of the nucleus is approximately one hundred thousand times smaller. Let's pretend we have a "classical" atom where both the atom and its nucleus have a defined position and size. (This it...

    Calculate X-Ray Wavelength for Lead Target

    Homework Statement The tube in a medical research X-ray unit uses lead (Z=82) as it's target. Assume the electrons are accelerated through the voltage calculated in part (b). What is the wavelength of the Kα line? Homework Equations KE=-13.6 ev ((Z-1)squared) / (1squared) KE=PE=VQ E=QV λ=hc/E...
