For example: Atoms: Na, H, Cu, O; Ions: (atoms with a charge): Na +1, Ca +2, Cl-1 These condensers use tubes that are usually made of stainless steel, copper alloys, or titanium depending on several selection criteria (such as thermal conductivity or corrosion resistance). The temperature at which vaporization (boiling) starts to occur for a given pressure is also known as the saturation temperature and at this conditions a mixture of vapor and liquid can exist together. The ionic compounds are divided into monovalent, divalent and trivalent ions on the basis of their valencies.
