Discussion Overview

The discussion revolves around the physical properties of lithium, particularly its magnetic and electromagnetic characteristics, as well as its state (solid or liquid) and reactivity. Participants explore various aspects including magnetization, behavior in electromagnetic fields, and chemical stability over time.

Discussion Character

  • Exploratory
  • Technical explanation
  • Debate/contested

Main Points Raised

  • One participant questions whether lithium can be magnetized and if it can be forced through a tube with a spiraling current, suggesting a potential application in electromagnetism.
  • Another participant corrects the initial claim about lithium being a liquid, stating it is solid at room temperature and provides its melting point.
  • A participant mentions lithium's paramagnetic susceptibility, indicating it cannot be magnetized.
  • Concerns are raised about lithium's stability, with one participant asserting that lithium does not break down over time but tarnishes quickly in air and reacts dramatically with water.
  • Another participant highlights lithium's use as a liquid metal coolant in power systems and its high boiling point, suggesting its potential in nuclear reactors.
  • Discussion includes the isotopes of lithium, noting their relative abundances and providing links for further information on nuclear properties.

Areas of Agreement / Disagreement

Participants generally agree that lithium is solid at room temperature and has specific chemical properties, but there is disagreement regarding its magnetization and the implications of its reactivity. The discussion remains unresolved on the potential applications of lithium in electromagnetic contexts.

Contextual Notes

Participants reference various properties of lithium, including its melting and boiling points, but there are limitations in the discussion regarding the definitions of terms like "break down" and the conditions under which lithium's properties are considered.

Who May Find This Useful

This discussion may be useful for those interested in the physical and chemical properties of lithium, applications in nuclear technology, and the behavior of alkali metals in various environments.

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?

Ummm...liquid ? No, lithium is very much solid. The melting point of Li is 181C or 357F.

Li has a paramagnetic susceptibility of 0.000014 at room temperature, so it can't be magnetized. Li does not break down over time (no metal that isn't naturally radioactive does), but it tarnishes (oxidizes) in air in a matter of seconds.

It reacts quite dramatically with water. Back in the day, I did atomic beam experiments with various alkali metals, including lithium. One way to clean the oven was to squirt water on it--good times! (Better wear goggles.)
 
As Gokul mentioned, Li has a low melting point (453.69 K [or 180.54 °C (356.97 °F)]), but it is obviously solid (but soft) at room temperature.

Li has been used as a liquid metal coolant in some demonstration power systems, and has been proposed for compact fast nuclear reactors because it has a high boiling point (1615 K [or 1342 °C (2448 °F)]) or a liquid range of 1161.31 K.

One can search here for properties of Li - http://www.webelements.com/webelements/elements/text/Li/key.html

Liquid metals are good conductors, so they can be pumped with electromagnetic pumps.

As Gokul and DocAl both mentioned, Li, like the other alkali metals is extremely chemically reactive, and in fact is the most reactive alkali metal.

There are two isotopes, Li6 with about 7.6% abundance of Li and Li7 with about 92.4% abundance. For more on the nuclear properties see
