Properties of Ionic and Covalent Compounds Worksheet Credit Recovery

Classify the properties listed below as either a property of ionic compounds only, a property of ionic and covalent compounds, or a property of covalent compounds only by clicking and the property and choosing the correction option. In the end, if you have classified the properties correctly, you should have12 properties of ionic compounds only,4 properties ionic and covalent, and13 properties of covalent compounds only. Properties of Ionic Compounds Only Bond is due to the gaining and losing (transfer) of valence electrons Conducts electricity when in a solution Forms an electrolyte solution Does not use prefixes to name compounds (except Hydrates) Typically a brittle solid at room temperature The order of atoms in the formula and name is determined by ionic charge (cation first, anion second) The elements in the compound can only bond together with one specific ratio Composed of a metal and a nonmetal Breaks apart into ions when dissolved in water generally a bond between two elements that are far apart from to each other on the Periodic Table (PT) High melting boiling points High Viscosity Properties of BOTH Ionic and Covalent Bonding involves valence electrons Bond to have a stable arrangement of electrons Bond to fill outermost energy levels Bond to have a valence electron configuration like the Noble Gases Properties of Covalent Compounds Only Composed of two nonmetals Uses prefixes to name the compounds generally a bond between two elements that are close to each other on the Periodic Table (PT) Some will dissolve in water (and some won’t) The order of atoms in the formula and name is determined by electronegativity value (less electronegative element first, more electronegative element second) Do NOT form electrolyte solutions Bond is due to the sharing of valence electrons Exists as solids, liquids gases at room temperature Does NOT conduct electricity when in a solution Low melting boiling points The same two elements can bond together in a variety of ratios Do NOT break apart into ions when dissolved in water (except for acids) Low viscosity
