![]() 3 Weeding out the words referring to negatively-charged species like heteropoly anion, medical terms like opisthocr anion, and some words that might be controversial in a student setting, we were left with a few words like f anion (would that be the fluoride anion?) and w anion. However, the Lots of Words site could only come up with 27 words. We had hoped to eventually present a comp anion list for words that end in “anion”. See the full list of "cations" in the Supporting Information The list of the “cations” chemists should know, containing the additional list of chemical transformations “cations,” is in the Supporting Information. We also found many words that contained chemical elements or compounds embedded in the words themselves (e.g., acidification and arsenication). ![]() We often separated out “-ification” words from the other “-cation” words to highlight the prevalence of that recurring pattern. cyberedu cation, misedu cation, and reedu cation) and placed the prefixes into a separate list. Along the way, we encountered many similar words with differing prefixes (e.g. We waded through the list and extracted words relevant to teaching and doing lab work in chemistry. 2 (WARNING: Some of the words might be controversial in a student setting.) A few of the words in this rather large list are words referring to positively-charged species like di cation, tetra cation, and poly cation, but many, many more of the words are a result of converting verbs to nouns. ![]() To view an impressive number of words that end in “cation”, we recommend the site Lots of Words, which provides a list of 1128 of these words. To assemble our cation word lists, we sought listings of words online. Small wonder that students get frustrated! Our hope is that with the cation-ending word lists we can make a point that learning chemical language is not really much different than learning words in any language and that learning the language of chemistry is a manageable task. But, sulfate ions become sulfuric acid, not sulfic acid, and phosphate ions become phosphoric acid, not phosphic acid. ![]() For example, in naming oxoacids based on the corresponding oxoanion, “–ate” endings convert to “-ic acid.” 1 So, nitrate ion becomes nitric acid and carbonate ion becomes carbonic acid. Compli cations are even present in the nomenclature that students need to learn. The words we use in chemistry also follow patterns with many exceptions. The English language also contains a maddening number of exceptions to its patterns. ![]() A verb ending in “-ify” can be converted to a noun ending in “-ifi cation.” For example, the verb edifiy becomes the noun edifi cation. A verb ending in “-cate” can be converted to a noun ending in “- cation.” For example, the verb locate becomes the noun lo cation. If students need to memorize lists of ions, why not have a little fun with it? We have organized lists of chemistry-related words that end in the letters “-cation” and have placed these lists in the Supporting Information for your enjoyment.Īs in any language, English words often follow patterns. In the English language, positively charged ions are called “cations” and negatively charged ions are called “anions.” Chemistry students invariably need to show dedi cation to memorizing lists of cations and anions. ![]()
