Anions. Determine the presence of a . cation. or anion by a chemical reaction. Determine the identity of . cations. and anions in an unknown salt. What . are. . Cations. ?. Sometimes certain metals (Na, K, . Which. is the atomic number?. What. does the atomic number tell us?. What. is the mass number?. What. does the mass number tell us?. How many protons does Potassium have?. How. many neutrons?. How. Remember. Ions are charged particles. Electricity flows due to the flow of electrons. You can think of electricity as a river and the water is the electron. Well, in an ionic solution, there is a flow of electrons as electrons are exchanging between . Pyfer. , Peter . Xu. IONIC RADIUS. IONIC RADIUS. The ionic radius is the measure of an atom's ion in a crystal lattice. Values for ionic radius are difficult to obtain and tend to depend on the method used to measure the size of the ion. What is an anion?. An ion that carries a negative charge. In the next 2 weeks we will look detecting the presence of some of these anions. We will look at . The Chloride Ion . Cl. -. The sulfate ion SO. The carbonyl group is electrophilic at the carbon atom and hence is. . susceptible to attack by nucleophilic reagents. Thus, the carbonyl group reacts as a . formyl. . cation. or as. . an . acyl . Monoatomic i on Ion Name Ion Old Name New Name H + hydrogen ion /proton Cr 2+ chromous ion chromium (II) ion Li + lithium ion Cr 3+ chromic ion chromium (III) ion Na + sodium ion Mn 2+ manganous ion For translating MS-based metabolomics to biology, we need to know quantity/concentrations of identified molecules. Q-. tion. can be used to model . metabolomic. networks and to see fluxes.. Ionization is a complex process and no all compounds are forming ions is the same way (NMR signal intensities are much less sensitive to the chemical structures differences).

Name as the root of the elemental name, ending in . –ide. Anion charges are determined from the element’s position on the periodic table. IONIC COMPOUNDS. To name an ionic compound name the cation, then name the anion. Membrane Properties chemical and electrical properties of biological membranes Jim Huettner Lecture Overview Selective permeability Osmolarity and osmotic pressure Ionic gradients Electrical properties: resistance and capacitance Oxyanions. Oxyanions- negative ions containing oxygen.. These have the suffix “-ate” or “-ite”. “-ate” means it has more oxygen atoms bonded, “-ite” has less. For example. SO. 4. 2-. sulfate. Adil. Hamid.
