... Fluorine is too reactive to give mono-fluorinated products For Iodine, an oxidizing agent such as hydrogen peroxide or a copper salt such as CuCl2 must be added to the reaction • These substances oxidize I2 to the electrophilic species that reacts as if it were I+ • The aromatic ring reacts with the ...

9.2 Oxidation Numbers
... 9.3 Types of Chemical Reactions Chemists often group reactions into general categories, rather than treating each chemical change as unique. For example, you saw in Chapter 7 that many chemical changes can be assigned to the category of precipitation reactions. Understanding the general characterist ...

... and protons. Since electrons have negligible mass, the entire mass of the atom was regarded as the mass of the proton only. Each proton has a mass of 1.67x 10-24 g which is taken as 1 unit mass. In 1920, Rutherford found that except for the hydrogen atom, the atomic masses of no other atom could be ...

Effective atomic numbers and electron densities of amino
... The idea of effective atomic number is to assume that a compound can for special purposes be regarded as being built up of one kind of species with atomic number Zeff .In materials like biological molecules and other compounds, for photon interaction a single atomic number can not represent the atom ...
