    B Cryogenic storage dewars and EM waves

    I was researching cryogenic storage dewars and read that, "All dewars have walls constructed from two or more layers, with a high vacuum maintained between the layers. This provides very good thermal insulation between the interior and exterior of the dewar, which reduces the rate at which the...

    B Question about Iron-56 binding

    Thanks for the info! So my understanding was that all matter would revert to Fe-56, rather than Ni-62, even though Ni-62 has a higher binding energy. Wikipeida states this as being due to the competition between photodisintegration and alpha capturing during nucleosynthesis. So does what you...

    Iron oxidation states

    Sorry for my ignorance. What is the difference between 'donate' and 'give up'?o_O I still can't understand why Fe would want to give up 3 electrons. So far I have only studied smaller elements (Ca and smaller) and everything made sense because, with the exception of hydrogen, all the elements...

    Iron oxidation states

    I guess what was (is) confusing me is the different electron configurations for Fe ions. I watched a video about it and my confusion is why Fe3+ is able to donate 3 electrons to form a compound like FeCl3 when it has 5 electrons in its outer shell (d)?

    B Question about Iron-56 binding

    As I understand you are saying that above a certain pressure an atom of Fe-56 does become unstable. In theory, is going beyond this critical pressure point what causes the collapse of an iron star into a neutron star?

    B Question about Iron-56 binding

    I read that all matter in the universe, through fission or fusion, will eventually create 'iron stars' comprised of 56Fe, which will then eventually collapse into neutron stars and black holes.

    B Question about Iron-56 binding

    Is it possible for two 56Fe atoms to fuse together? As I understand they won't. So what happens when the two atoms undergo extreme heat/pressure? Do they break down into neutrons?

    Question about Calcium Nitride

    Thank you again for all your feedback! I'm grateful that everyone here takes the time to respond to my questions, seeing as how nobody is paid to do so. Any type of feedback is always valuable to me because there is always something I can learn from it. And even if I can't understand anything...

    Iron oxidation states

    I saw on Wikipedia that Fe has both positive and negative oxidation states. I know that Fe will willingly give up its 2 electrons to form an ionic bond with O for example, making it Fe+2. 1. But how can Fe+3 exist? This means it gives up three electrons right? Does this mean the Fe atoms...

    Question about Calcium Nitride

    I'm not sure why but I can't see the structure with that article either. Maybe you have to be logged in as well, or maybe I have no idea what I'm doing.o_O Anyway, I think I know what it looks like. Thanks again
