Lewis dot structure of a Hydroxide ion compared to a hydroxyl radical. In chemistry, a radical, also known as a free radical, is an atom, molecule, or ion that has at least one unpaired valence electron. [1] [2] With some exceptions, these unpaired electrons make radicals highly chemically reactive. Many radicals spontaneously dimerize. Most ...
A mnemonic is a memory aid used to improve long-term memory and make the process of consolidation easier. Many chemistry aspects, rules, names of compounds, sequences of elements, their reactivity, etc., can be easily and efficiently memorized with the help of mnemonics.

The 'fire' radical, 火, is used as the semantic category. The character for entropy, 熵 (pinyin: shāng), is derived from 商 (pinyin: shāng), which means 'quotient' in this context. This recognizes the Clausius equation for the differential change in entropy as the differential heat absorbed divided by the temperature: dS = dQ / T .

Also acid ionization constant or acidity constant. A quantitative measure of the strength of an acid in solution expressed as an equilibrium constant for a chemical dissociation reaction in the context of acid-base reactions. It is often given as its base-10 cologarithm, p K a. acid–base extraction A chemical reaction in which chemical species are separated from other acids and bases. acid ...
Is it possible to live comfortably in retirement on Social Security income alone? Yes and no. Alden and Dena Swartz draw nearly $4,000 a month from Social Security, the government program designed ...
The most common method for accessing radical anions is through the use of reducing agents. Synthesis of phosphorus-centred radical anion via reduction usgin K or Li by Wang and co-workers. Synthesis of diphosphorus-centred radical anion and the di-radical di-anion via reduction with KC8 by Wang and co-workers.
