WLMPT - Periodic Table Math Mystery Cache

WLMPT - World's Longest Mystery Power Trail is a collaborative series of caches started by CinciChewbacca. The goal is to form the world's longest line of mystery caches. Feel free to contribute by creating a puzzle with starting/false West coordinates of W 84 18.000. We hope that a diverse collection of puzzles will give people something to do in this time of distress. Happy puzzle caching!  

This contribution to the WLMPT incorporates my two main skill subjects of chemistry and mathematics, based on the Periodic Table of Elements. The best organization of the elements known at that time came from Dmitri Mendeleev in 1869, when he ordered elements by their atomic weight and predicted the properties of as-yet-undiscovered elements that fit into the gaps of his table. Eventually, the elements were ordered by atomic number instead of weight, and common properties among groups and periods were identified. After many decades of scientific arms races between the United States and the USSR/Russia, in November 2016, the International Union of Pure and Applied Chemistry finalized their approval of the last four elements needed to complete the bottom row of the Periodic Table. And so it waits completely full until researchers can crack the code to reach into a whole new world...

Nitrogen =

[Actinium_period × Bromine_{atomic weight} × Caesium_{atomic number}] +

[Tennessine_{number of electron shells} × Uranium_{atomic weight} × Vanadium_group] -

[Tungsten_{atomic weight}] + [Xenon_{atomic weight}] +

[Ytterbium_{atomic weight} × Zinc_{atomic number} / Yttrium_group] -

[Xenon_group] - [Zinc_{atomic weight}] -

[Ytterbium_{atomic number} × (Xenon_period + Yttrium_period + Ytterbium_period + Zirconium_period)]

Tungsten =

[Copper_{atomic number} × Copper_{atomic weight}] +

[Tin_{number of electrons} × Tin_{atomic weight}] +

[Tin_period × Tin_{number of valence electrons} × Gold_{atomic weight}] -

[Gold_{atomic number} × (Silver_{atomic number} - Silver_{number of electron shells})] +

[(Silver_{atomic weight} + Platinum_{atomic weight}) / Platinum_group] -

[number post-transition metal elements]

**If you choose to park at the business instead of the park, please respect them and cache outside of workday hours and also be careful crossing the street.**
