Should Neutron Stars be Added to the Periodic Table?

  “It is a truth universally acknowledged that no physics problem is complete unless some major component of reality is excluded to simplify the numbers.”

  I’ll save this quote for my students. Amazing.

    The air vent is actually a particle accelerator shooting neutrons into the periodic table.

    I’ve never seen a reverse-Saddam and I am delighted to say that I’m glad it was in this community.

  After reading I realised that this proposal isn’t a single new element for all neutron stars, but a separate new entry on the table for every individual neutron star in existence, unless there are two that happen to have the exact same number of protons which is unlikely. Sounds good to me

      we have assumed that Rex is comprised of a uniform nucleon fluid, with protons, neutrons and electrons in an idealised 1:8:1 ratio

      This is how the author is estimating it, they are assuming 1/9th of the mass is protons. No idea how good that assumption is though, there is a source which doesn’t look the most convincing

  Do they have protons or only neutrons? because if there are no protons then it is technically just neutronium and not an element,

  If they do have protons, then it is safe to assume it is a ridiculous number like 10^40. in which case I would count it as an element. And given how unlikely is for 2 neutron stars to share the number of protons, then every single neutron star is its own element,

  Are they elements? 🤨

    And also, because they do not react with other atom, and if 2 collide then they merge their nucleus, we can agree that they are non reactive, and therefore we can consider them noble gasses…

    Wait, are they gas?

    YES, they are, if there is a single atom floating in space I think that counts as a gas

  A representation of a binuclear compound of element 10^(56) with an average bond length of 100 quintillion angstroms.

  Okay that was funny.

  This collapse generates a body of neutron-removed matter with a radius as small as 10 km, but a mass comparable to our Sun’s. As such, they are the densest known material outside of Twitter, at around 1017 kg/m3. For American readers unfamiliar with SI units, that means a pair of truck-nuts made of neutron star would weigh as much as ten million aircraft carriers.

  Shouldn’t they be element 0 as they dont have any protons?

  • sm1dger@lemmy.world ⁨10⁩ ⁨hours⁩ ago

    The conversion from protons to neutrons does not complete 100% so there are still some (trillion) protons left per “atom”

  Hum… The width of each row increases exponentially with their number.

  It’s probably just some ~1m away from the small elements.

  Do they have 0 protons? Because if they do, they should be in the spot above helium

    No the ratio of protons neutrons electrons is assumed to be 1:8:1 in the article. It’s a fun read
