Even the atomic weight of the 24th and 25th element tells u something deeper.......54 and 55.......like 5/4 from Euler's product with an s of 1...............5/4 is the 3rd term.....like a pythagorean triple.......a 3, 4, 5 right triangle............the metals and the non metals even...metals make up 80 percent......4/5 = 0.80.......like a 45/45 right triangle....
