Cation A positive ion

Cathode rays the "rays" emanating from the negative electrode (cathode) in a partially evacuated tube a stream of electrons. (2.4) Cathodic protection a method in which an active metal, such as magnesium, is connected to steel to protect it from corrosion. (18.6) Cation a positive ion. (2.6)... [Pg.1092]

Electrons with a high kinetic energy can ionize molecules. An outer electron is removed from the molecule, leaving an unpaired electron and thereby forming a radical cation a positive ion with an unpaired electron (Figure 11.77). [Pg.423]

Cation A positively charged particle or ion. Channeling Cleavage and furrowing of the bed due to faulty operational procedure, in which the solution being treated follows the path of least resistance, runs through these furrows, and fails to contact active groups in other parts of the bed. [Pg.436]

Cation a positively charged ion it migrates to the cathode in a galvanic or voltaic cell. [Pg.1365]

Cation A positively charged ion that migrates naturally to a cathode. [Pg.118]

The radical cation of benzene has been produced by y irradiation of benzene adsorbed on silica gel (62, 63). The seven-line spectrum shown in Fig. 24 is expected for a molecule having six equivalent protons. An experimental coupling constant of 4.4 G, compared to a value of 3.75 G for the negative ion, gives strong support for attributing the spectrum to a positive ion. The g value is also consistent with this assignment. [Pg.305]

An electrically charged atom or group of atoms. An atom which loses an electron becomes a positive ion (cation) and one which gains an electron becomes a negative ion (anion). In electrolysis anions are attracted to the anode and cations to the cathode, lonomer... [Pg.35]

Ionic polymerisation can be categorised into two classes, (i) Cationic polymerisation and (ii) Anionic polymerisation, depending upon the nature of ions used for the initiation of polymerisation. The cationic polymerisation refers to the process in which a positive ion is used for initiation. When a negative ion is used for initiation of polymerisation, then process is referred to as anionic polymerisation. [Pg.234]

Ionic compounds result from the combination of a positive ion known as a cation and a negative ion called an anion. Salt is an ionic compound in which sodium cations and chloride anions chemically combined. Molecular compounds contain discrete molecular units. Molecular units or molecules are the smallest unit of a molecular compound. Atoms in a compound are held together by covalent bonds. Bonds dictate how atoms are held together in a compound or molecule, but for now, just think of ionic compounds as compounds composed of ions, and molecular compounds as compounds composed of molecules. Sugar, water, and carbon dioxide are examples of molecular compounds. [Pg.50]

Cathodic Protection method where a more active metal is connected to a metal structure such as a tank or a ship protecting the structure because the active metal is oxidized rather than the structure Cation a positively charged ion Cellulase a group of enzymes that hydrolyze cellulose... [Pg.337]

Cationic polymerization A process in which the active end of the growing polymer is a positive ion. [Pg.251]

Explain the loss of CO from the parent ion and indicate if, by loss of C2H4, a positive ion, a radical or a cation-radical must result. [Pg.328]

CATION. A positively charged ion. Cations are those ions that are deposited, or which lend to be deposited, on the cathode. They travel in the nominal direction of the current. In electrochemical reactions they are designated by a dot or a plus sign placed above and behind the atomic or radical symbol as H or H+. the number of dots or plus signs indicating the valence of the ion. [Pg.307]
