Elemental Names

So, I decided to make a list of the possible shortenings for characters who are named after an element. Why? Because I like characters with names like that, and so here’s a list of how their names can be shortened.

Some were relatively easy (Samarium becomes Sam, for instance, or Neon becomes Neo), but others were harder to come up with. A few, in bold, I couldn’t figure out at all (tin, lead, germanium, or zirconium), and, of course, if you have any suggestions that aren’t on here, feel free to reply with them or send an ask or whatever.

Names below the cut - I only went up to 92, Uranium, because after that all the elements are named after people or places, and so there’s not much use in making names that go with them)

Description of Inorganic Chemistry

Inorganic chemistry is a dynamic and fascinating field of chemistry growing at a rapid pace in both research and theoretical aspects. The lusty impact of this field has introduced the subject as an essential part of the curricula of all universities. The first edition of Inorganic Chemistry aims to provide the essentials of the subject in an easy and understandable manner. The book is an outcome of the teaching and research experience of the authors so that students can learn concept formulation instead of just rote memorization. The book is primarily aimed for students at undergraduate (BSc pass and honors) and postgraduate (MSc pass and honors) levels taking inorganic chemistry as a special subject for a one-semester or a full-year course. Inorganic Chemistry book is designed to provide concise information about various aspects of inorganic chemistry that can also be used by students from various fields involving inorganic compounds, such as environmental science, polymer science, industrial chemistry, bioinorganic chemistry, and metallurgy. However, they can skip the irrelevant topics as per their field. Inorganic Chemistry book will also be a source of reference for the students doing BTech courses or taking inorganic chemistry as an ancillary subject. It will also be helpful for the challenging requirements of various competitive exams such as CSIR, SLET, and GATE. The content of the Inorganic Chemistry book has been framed in an easy-to-understand language that would generate interest in the subject. All the chapters provide descriptive information and are enriched with illustrations, comprehensible articles, solved examples, both numerical as well as theoretical, to satisfy the needs of students. At the end of each chapter, a concise summary has been given for quick revision before examinations. The chapters have been enriched with exercises comprising theory-based general questions and objective-type questions to provide an insight into the examination pattern. The book introduces descriptive and illustrative information about structure of atoms and nuclei, radioactivity, chemical bonding, molecular symmetry, structure of solids, redox reactions, non-aqueous solvents, acids and bases, extraction of elements, Periodic Table, chemistry of known elements, coordination chemistry, organometallics, inorganic polymers, bioinorganic chemistry, environmental chemistry and analytical chemistry. Although it is very difficult to include such a vast subject in a single book, a reasonable attempt has been made to cover a variety of important topics. We hope the Inorganic Chemistry book will prove very helpful in providing the complex concepts of inorganic chemistry in an easy way.
