Document Summary
Made up of positive and negative ions. Made up of molecules held together by intermolecular attractive forces. Made up of metal atoms held together by metallic bonds. These bonds are formed by the overlap of metal atomic orbitals. There are regions of high electron density, which are very mobile and move freely from atom to atom. Process of conversion of molecules in the solid state directly to the gaseous state. An example is dry ice, which is solid carbon dioxide. It will convey directly to a gas at atmospheric pressure. Any homogeneous mixture of two or more substances. The components of a solution that is present in lesser quantity. The solution component present in the largest quantity. Solutions can be liquids as well as solids and gases. Air - oxygen and several trace gases are dissolved in the gaseous solvent nitrogen. Alloys - brass and other homogenous metal mixtures in the solid state.
