Next little point - the Group numbers. Roman Numerals are fine in principle here, but regrettably they led to confusion when used in Anglice:

"Group numbers
"There are three systems of group numbers; one using Arabic numerals, another using Roman numerals, and one using a combination of Roman numerals and Latin letters. The Roman numeral names are the original traditional names of the groups; the Arabic numeral names are a newer naming scheme recommended by the International Union of Pure and Applied Chemistry (IUPAC). The IUPAC scheme was developed to replace both older Roman numeral systems as they confusingly used the same names to mean different things."

The Roman numerals system also had no numbers for all the transitional metal groups (those not-very-rare metals such as Fe and Cu).

Let's add (or, even more radically, substitute) the modern standard "Arabic" numerals.

Iam in saeculo XIX hoc elementum latine descriptum est non nullis in dissertationibus, quarum plures et veteriores formam cum i adhibent. (e. g. Herrklotsch 1845, Hilbeck 1833) Inde hoc praeferendum censeo.
