Hutcheon Right Step Periodic Table

From Scott Hutcheon's Linkedin Website:


"Built from first principles, the RSPT is the only Periodic Table (so far) that reflects the periodicity of radioactive elements (natural and artificial) including Tc-Np and Cf/Es, the periodicity of liquids and gases (at standard and other conditions), depicts the 5 and 8 mass roadblocks, and finally clarifies the positions of the initial propagating elements H, He, and Li-Be/B in accordance with their cosmic and stellar evolutionary origins.

"Name inspired by the Janet Left Step Periodic Table (LSPT).

"Bonus Easter Egg: SPOCH BONSe, pronounced Spock Bones, is a new mnemonic device to remember the updated elements considered most essential for human life. Also considered POSCH SeNOB and SNOBS ePOCH."
