The International Year of the Periodic Table
In 2019 we celebrate the 150th anniversary of the Periodic Table of Elements. The table was not âdiscoveredâ, but rather it was formulated by Dmitri Mendeleev, based on his knowledge of how elements are related to each other and can be classified in groupings (in this case, vertical columns) as they display similar properties. And while there were gaps in the horizontal rows, or periods, of his table, Mendeleev proposed that these gaps were not mistakes, but rather that they represented elements that had not yet been discovered. He was able to predict with great accuracy the atomic weights and properties of these âmissingâ elements, and as more of these elements were discovered over the decades, his predictions were proven to be surprisingly accurate.
Your task in solving this mystery is to figure out where the cache container is hidden based on the following data:
- How many elements were there on Mendeleevâs first table back in 1869?
- How many elements comprise the 2019 version of the Periodic Table of Elements?
To reveal your final coordinates, use your answers to solve the following: N 49 22. (10A + A)Â W 123 16. (7A + 3B)
Please be very careful where you park. Thanks to a few careless tradesmen who used to park beside where they were working in the area, the locals don't take too kindly to visitors who park illegally, even if it's "just for a few minutes".
