CHM 101 Chapter Notes -Ionic Compound, Strong Electrolyte, Nonmetal
Document Summary
Learning objectives: recognize and distinguish between molecular and ionic compounds, predict the formulas and charges of simple ions and oxoanions. Be able to name and write formulas for the commonly-encountered polyatomic ions (co32-, no3-, po43-, so42-, clo3-, Ionic compounds are named by listing the name of the cation first, followed by the name of the anion: for ionic compounds that contain a metal that can exhibit multiple charges, a. Roman numeral is inserted inside parentheses after the cation name to indicate the charge. In naming molecular compounds, the first atom in the formula (the element farthest down or to the left in the periodic table) is named first with the second element named as if it were an anion. Electrolyte (3. 1)- a substance that dissociates or ionizes into aqueous ions upon dissolving and conducts electricity wen dissolved in water. Nonelectrolyte (3. 1)- a substance that retains its molecular identity upon dissolving and does not conduct electricity when dissolved in water.
