+## Description
+
+The [IUPAC Periodic Table of the Elements](https://iupac.org/what-we-do/periodic-table-of-elements/)
+is one of the most recognizable features of modern chemistry - the organization
+of all known chemical elements along with some of their most fundamental
+properties, together with their names and symbols. Today we're going to use
+that as we spell some words.
+
+Here's the list of the elements alphabetized by the element's name. We can also
+see the symbol (1 or 2 letters - we're omitting the emerging elements that
+often contain three letters), atomic number and weight, and Pauling
+Electronegativities (c), which are unused in this challenge.
+
