    found on chromosome 7‚ and controls the secretion of chloride‚ sodium‚ and bicarbonate ions across the epithelium tissues. The gene is required to regulate the components of sweat‚ digestive juices‚ and mucous. The product of the gene is a halide anion channel that contains two ATP-hydrolyzing domains‚ which allows protein to be used as energy in the form of ATP. Only one normally functioning gene is required to prevent cystic fibrosis. The disorder develops when neither of the two genes works appropriately

    Alkali Metals Introduction Alkali metals refer to six elements belonging to the Group IA of the long form of the Modern Periodic Table‚ viz. Lithium (Li)‚ Sodium (Na)‚ Potassium (K)‚ Rubidium (Rb)‚ Cesium (Cs) and Francium (Fr). Fr is a radioactive element. These elements are called so because they form strongly alkaline oxides and hydroxides. Electronic Configuration of Alkali Metals Each of the alkali metals has one electron in their outermost (valence) shell‚ which is just outside an inert

    Chemistry Notes: Metals: • A metal consists of a lattice of positive ions surrounded by a ‘sea’ of mobile delocalised valence electrons. • Metallic bonding is the electrostatic attraction between the delocalised electrons and the positive ions in the metallic lattice. Properties of metals: Property Explanation Relatively high density The particles are very close together. This is because of high electrostatic forces between the sea of valence electrons and the positively charged nucleus.

    Experiment 3: Electronic structure‚ bonding and shape of some simple inorganic molecules. Introduction: In quantum chemistry‚ electronic structure is the state of motion of electrons in an electrostatic field created by stationary nuclei. The term encompass both the wave functions of the electrons and the energies associated with them. Electronic structure is obtained by solving quantum mechanical equations for the aforementioned clamped-nuclei problem. Electronic structure problem arise from the

In chlorobenzene‚ each carbon atom of benzenering is sp2 hyridised and is electron withdrawing. Chlorine atom donates a lone pair of electron and acquire positive charge. The negative charge is delocalised on ortho and para position by resonance. C-Cl bond acquires partial double bond character and is 169 pm as compared to 17.0 pm in chloromethane
