“…He proposed that the formation of metal was caused by a substance, called "phlogiston." According to Stahl, the converse process of heating a metal in the air to form its oxide caused the release of phlogiston into the atmosphere (Sukopp, 2018). Fifty-four years later, the French chemist, Louis-Bernard Guyton de Morveau performed careful experiments showing that, during combustion, metals increase in weight.…”

The term "oxidation number" and related concept such as "electronegativity" and "formal charge" appear frequently in both elementary and advance chemistry text. However, it is evident from the literature (or textbooks) that these terms are often viewed to be synonymous. Incomplete explanation of the fundamental concept of oxidation number can lead that conclusions pertaining to such a misleading interpretation. This research was conducted to review the concepts from common used high school chemistry textbooks and these concepts were then transformed to 6 number open minded problems. These problems were then tested to 40 first semester chemistry program students in the University of Jambi who joining Basic Chemistry course. The result was about 80% of students give the right answer in determining oxidation number (problem number 1). But, in the certain molecule (problem number 2) they can't determine correctly because they couldn't use the "Rule" from initial understanding in high school. For the next problem (4a), none of the students give the right oxidation number of an atom and all of them can't explain precisely correlation among oxidation number, electronegativity, and formal charge. The intent of this paper is to clarify the notion of oxidation number, electronegativity, and formal charge, describe their relationship (especially for high school chemistry textbooks), and criticize upon misleading application.

This work is the critical edition of the catalog of Holy Roman Emperor Leopold’s II mineralogical collection. The volume, unpublished and preserved at the Historical Archives of the University of Firenze Museum System, dates to 1765 and describes 242 mineralogical specimens coming primarily from the current Slovak-Hungarian mining district. This edition gives the transcription of the German manuscript and its translation into English together with an organized system of notation to illustrate the complex history of the text, the characterization of the mineralogical species, and the geographical location of the mineral extraction sites. This work represents to date the only published catalog of a mineralogical collection belonging to a member of the Habsburg-Lorraine family.
