Talk:2100: Models of the Atom

No mention of the Platonic solid model? DanielLC (talk) 05:56, 18 January 2019 (UTC)

   Not yet. My favorite of those 5 is the double cube, AKA the Octahedron. Haph (talk) 06:35, 18 January 2019 (UTC)

My good sir DanielLC: I presume that Randall neglected to mention it because the first evidence-based atom theory didn't come until 1810 and John Dalton. The atom theories of the ancient Greeks were mostly philosophical posturing, in my opinion.

We seem to be missing the [Acorm Atom] as well. Kazzie (talk) 10:16, 18 January 2019 (UTC)

According to [lecture notes by the astronomer Neil Trentham], mass in the universe ist 75% H (mostly 1p+0n=1) and 25% He (mostly 2p+2n=4). As He is 4 times as heavy and 3 times as seldom, there is 12 times more H than He => The ratio n/p is 1/7. We can assume that in the 538 model the statistics was done on atoms comprising few Hydrogene, e.g. only the earth's mantle. In heavier elements the ratio n/p > 1.

What are the numbers? Is 173 an error for 137, the fine structure constant?
