The students will learn how ionic compounds form and how metallic bounding affects the properties of metals. Ionic compounds Notes Enthalpies- it is equal to the internal energy of the system plus the product of pressure and volume. Brittle- hard but liable to break or shatter easily. Dissociated- disconnect or separate. Repulsion- a feeling of intense distaste. Insulators- a thing or substance used for insulation, in particular. Aqueous- of or containing water, typically as a solvent or medium. Metal+Nonmetal Cation+Anion Cation(metals) Anion(nonmetals) Ionic compounds can turn into a solid by forming into a crystal It take a lot of heat and high temperatures to melt ionic compounds Since the ions are strong it’s hard to split but with pressure in involved it’s able to split the crystal. Ionic compounds have a weakness but give off energy which is H 2 0 Ionic solids don’t produce energy because the bounds are so tight together Metal with nonmetal CaO Calcium Oxide Also end it with IDE BaF 2 Beryllium Florid Uses prefixes
Here are the properties shared by the ionic compounds. Notice that the properties of ionic compounds relate to how strongly the positive and negative ions attract each other in an ionic bond. Ionic compounds form crystals. Ionic compounds form crystal lattices rather than amorphous solids. Although molecular compounds form crystals, they frequently take other forms plus molecular crystals typically are softer than ionic crystals. Ionic compounds have high melting points and high boiling points. High temperatures are required to overcome the attraction between the positive and negative ions in ionic compounds. Therefore, a lot of energy is required to melt ionic compounds or cause them to boil. Ionic compounds have higher enthalpies of fusion and vaporization than molecular compounds. Just as ionic compounds have high melting and boiling points, they usually have enthalpies of fusion and vaporization that may be 10 to 100 times higher than those of most molecular compounds. The enthalpy of fusion is the heat required melt a single mole of a solid under constant pressure. The enthalpy of vaporization is the heat required for vaporize one mole of a liquid compound under constant pressure. Ionic compounds are hard and brittle. Ionic crystals are hard because the positive and negative ions are strongly attracted to each other and difficult to separate, however, when pressure is applied to an ionic crystal then ion of like charge may be forced closer to each other. The electrostatic repulsion can be enough to split the crystal, which is why ionic solids also are brittle. Ionic compounds conduct electricity when they are dissolved in water. When ionic compounds are dissolved in water the dissociated ions are free to conduct electric charge through the solution. Molten ionic compounds (molten salts) also conduct electricity. Ionic solids are good insulators. Although they conduct in molten form or in aqueous solution, ionic solids do not conduct electricity very well because the ions are bound so tightly to each other.
