Propteries of Compounds subunit

• Polarity results in the distribution of electrical charger over the atoms joined by a chemical bond
• In a chemical bond, polarity arises from the electronegativities of the elements
• Electronegativity is the ability of an atom to attract electron toward itself in a chemical bond
• A polar solvent attract each of the ions of an ionic compound and pull the ions away from one another.
• Ionic compounds are less soluble in solvents that contain a common ion
• COmpounds that have similar properties tend to dissolve in each other
• Organi compounds are mostly found in covalent compounds
• Ionic compounds are a good conductor of electricity when dissovled in water because of the presence of mobile ions
• Mobile ions are solid electrolytes
• Ionic compounds are a good conductor of heat because the ions are all next to each other
• Covalent compounds are good insulators of both electricity and heat because they have moleculues not as tightly held to each other
