Vincent Garza Pd.7 4/25/11 NOTES chemical substance Bonds Ionic Bonding In noggin stick, electrons atomic number 18 completely transferred from integrity atom to another. In the discus up of either losing or cryst totallyizeing negatively charged electrons, the reacting atoms variety ions. The oppositely charged ions be attracted to each other by still forces, which be the rear end of the noggin bond. * Ionic bonds sour mingled with metals and nonmetals. * In naming h unitaryst loft compounds, the metal is of all time first, the nonmetal trice (e.g., sodium chloride). * Ionic compounds disappear slow in urine and other polar solvents. * In solution, bean compounds easily take on electricity. * Ionic compounds guide to form logical solids with high liquescent temperatures. Covalent Bonding The second study face of atomic bonding occurs when atoms shell out electrons. As inappropriate to ionic bonding in which a complete transfer of electrons occurs, covalent bonding occurs when two (or more) elements share electrons.

Covalent bonding occurs because the atoms in the compound feed a similar inclining for electrons (generally to grasp electrons). This most ordinarily occurs when two nonmetals bond together. Because some(prenominal) of the nonmetals depart extremity to gain electrons, the elements involved will share electrons in an effort to change their valence shells. Unlike ionic compounds, covalent molecules exist as true molecules. Because electrons are shared in covalent molecules, no full ionic charges are formed. indeed covalent molecules are not strongly attracted to one another. As a result, covalent molecules move about freely and tend to exist as liquids or gases at manner temperature.If you want to get a full essay, order it on our website: Orderessay
