Did Mendeleev really design his table to represent the way electrons are arranged in atoms? In 1869, he must have been quite a visionary!

β | :Oh no, he didn't. He did by patterns of their properties. Also by atomic weights, but those were imprecisely known then, also note the isotope paradox problem (e.g. K and Ar must be swapped). The first sorting already guarantess to represent the electronic arrangement to some degree. BTW, lanthanides and actinides need more love. For starters, I PhD'ed on them. | + | :Oh no, he didn't.

Clearly these new elements are fractional elements, with elements having - for instance - 1 3/16 protons, etc. [[Special:Contributions/108.162.241.248|108.162.241.248]] 21:20, 13 October 2019 (UTC) | Clearly these new elements are fractional elements, with elements having - for instance - 1 3/16 protons, etc. [[Special:Contributions/108.162.241.248|108.162.241.248]] 21:20, 13 October 2019 (UTC) |
