    Number of consonants denotes number of oxygen atoms. Number of vowels denotes negative charge quantity. Inclusion of the word "ate" signifies that each ends with the letters a-t-e. To use this for the -ite ions, simply subtract one oxygen but keep the charge the same.

  3. Chain letter - Wikipedia

    en.wikipedia.org/wiki/Chain_letter

    A chain letter is a message that attempts to convince the recipient to make a number of copies and pass them on to a certain number of recipients. The "chain" is an exponentially growing pyramid (a tree graph ) that cannot be sustained indefinitely.

    The smallest repeating portion is a CRU, so all such possibilities are identified (including multiple directional possibilities for the chain). For the preceding polymer, they are: The subunits that make up each of these structures are identified, i.e., the largest divalent groups that can be named using IUPAC nomenclature of organic chemistry.

  5. Chain transfer - Wikipedia

    en.wikipedia.org/wiki/Chain_transfer

    In polymer chemistry, chain transfer is a polymerization reaction by which the activity of a growing polymer chain is transferred to another molecule: [1] [2] + + where • is the active center, P is the initial polymer chain, X is the end group, and R is the substituent to which the active center is transferred.

    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 ...

  7. Catenation - Wikipedia

    en.wikipedia.org/wiki/Catenation

    In chemistry, catenation is the bonding of atoms of the same element into a series, called a chain. [1] A chain or a ring may be open if its ends are not bonded to each other (an open-chain compound), or closed if they are bonded in a ring (a cyclic compound). The words to catenate and catenation reflect the Latin root catena, "chain".

  8. Chain reaction - Wikipedia

    en.wikipedia.org/wiki/Chain_reaction

    Another metaphor for a chain reaction is the domino effect, named after the act of domino toppling, where the simple action of toppling one domino leads to all dominoes eventually toppling, even if they are significantly larger. Numerous chain reactions can be represented by a mathematical model based on Markov chains.

    Glycine also does not have a β-carbon, while every other amino acid does. The α-carbon of an amino acid is significant in protein folding . When describing a protein, which is a chain of amino acids, one often approximates the location of each amino acid as the location of its α-carbon.
