    formed through an electrostatic attraction between two oppositely charged ions. Ionic bonds are formed due to the attraction between an atom that has lost one or more electron (known as a cation) and an atom that has gained one or more electrons (known as an anion). Usually‚ the cation is a metal atom and the anion is a non-metal atom. It is important to recognize that pure ionic bonding - in which one atom "steals" an electron from another - cannot exist: all ionic compounds have some degree of covalent

    Subject: Chemistry Topic: The Periodic Table The periodic table is a classification of all the elements based on ATOMIC NUMBER. It is composed of HORIZONTAL PERIODS and VERTICAL GROUPS which contain the elements arranged: *the order of INCREASING ATOMIC NUMBER *in the relation to the ELECTRON STRUCTURE of the atoms *in the relation to their CHEMICAL PROPERTIES (Criteria Used For Placing ELEMENTS in the Periodic Table) 1. ATOMIC NUMBER 2. NUMBER OF SHELLS (PERIOD) 3. NUMBER OF OUTER

    The Organic Matter present in the soil. 2. How does CEC buffer nutrient concentration in soil solution? CEC will exchange ions continuously between the solution concentration until both of the concentration has neutralized. 3. Why does anion adsorption appear to be of little importance in most agricultural soils? Why are AECs of ultisols usually greater than those of mollisols? CEC has a much larger impact for most agricultural soils. AEC occurs on the edges on minerals where positive

    valence electrons in order to achieve a stable electron arrangement. When a metal atom loses electrons it forms a positive ion or cation. When nonmetals react they gain one or more electrons to reach a stable electron arrangement. When a nonmetal atom gains one or more electrons it forms a negative ion or anion. The metal cations donate electrons to the nonmetal anions so they stick together in an ionic compound. This means that ionic bonds are formed by the complete transfer of one or more electrons

    Each group prepared unknown amino acid hydrochloride. The pre-prepared basic solution was slowly added to the amino acid solution and pH change was closely observed using the pH meter. During these titrations the amino acid converted from cation to zwitterion to anion; zwitterion is an amino acid with a net charge of zero. The identity of the unknown amino acid was determined by establishing a titration curve with the pKa values and pI point and molecular weight were either directly or indirectly found
