    Lithium Properties: Magnetic & Electromagnetic Properties

    trying to understand the physical properties of lithium, since it is a metalic liquid, Can it be magnetized? Could it be forced through a tube that has a current spiraling around it, like in an electromagnet? Does it break down over time, and what happens to it if it does?

    Velocity of Lithium Atom Powered by 1mW Laser Beam

    A lithium atom (mass doesn't matter) is being pushed from rest by a laser beam whose power is 1mW. Find the velocity of this lithium atom as a function of time So here goes what i have done v(t) = \frac{1}{2} at^2 now F = ma = \frac{\Delta p}{\Delta t} so then a = \frac{\Delta...

    Understanding Berylium and Lithium Ionisation Energy: Confusion Cleared

    Hello all I was asked a question on the first ionisation energy of Lithium and berylium, and it confused me. It seemed obvious to other people in the class that Berylium has a higher ionisation energy than Lithium (which according to my chemistry teacher is the right answer) Now This...

    How Do You Calculate the Speed of a Proton and Alpha Particle from a Decaying Lithium Isotope?

    I seem to be stuck on this problem. I thought calculating the velocity of the center of mass of the system would get me somewhere, but I remain confused about where to go next. Here is the problem: The light isotope, 5^Li is unstable and breaks up spontaneously into a proton (hydrogen nucleus)...

    Under abundance of lithium may solve existence DM

    http://arxiv.org/PS_cache/hep-ph/pdf/0306/0306024.pdf Cold dark matter may be made of superweakly-interacting massive particles, superWIMPs, that naturally inherit the desired relic density from late decays of metastable WIMPs. Well-motivated examples are weak-scale gravitinos in...

    Why do I never see anything made out of a lithium compound?

    I was in chemistry class today and I wasn't really paying much attention because its all quite simple stuff we're doing (systems in equilibrium) and my professor mentioned a Lithium compound that got me thinking. Why do I never see anything made out of a lithium compound? Its directly...
