    explained it better than my chemistry teacher. thank you.

    This type of counter intuitive phenomenon is why one might hope for an "island of stability" somewhere out beyond our current list of elements.

      I, too hope we find this island of stability one day, but I'm not holding my breath. The island of stability (if we ever reach it) will probably prove to be one consisting of elements with half-lives of seconds or fractions of seconds in an ocean of isotopes with half-lives so short that they are immeasurable. It was a hopeful concept in its day, and one that fueled great research into the transuranic and the super heavy elements. I'm sure many-a-grant-proposal featured this prospect in the 80's, 90's and even early 21st century. However, I would be surprised if we ever find anything significantly beyond oganesson with a half-life long enough to study. I think we would have made some progress by now. Then again, I'm sure Seaborg and his contemporaries got tired of hearing the same thing about the next element of row seven from people like me again and again..... yet they persevered... so, hope springs anew.

    What are the properties of Lanthanides, e.g. supraconductivity, isolation, magnetic, spin, etc. ... ?

    You'd think there'd be so much information on the internet but all there is are surface level explanations that don't even explain it. Just "because of transition contraction" without explaining how that works
