The low values (23 to 30 dynes/cm) result in easy wetting of most materials, which is helpful for. lubricity and other properties. Electrical Properties. The typical volume resistivity of Halocarbon oil is in the range. of 1013 to 1014 ohm-cm. The dielectric constant is quite low.
When metals form ions, they tend to do so by losing their electrons  to gain a positive charge. Losing negatively charged electrons  causes the metals to become more positiv â¦ e due to having more  protons.
Three points should be kept in mind, however. 1  The alkaline-earth metals tend to lose two electrons to form M 2+ ions (Be 2+ , Mg 2+ , Ca 2+ , and so on). 2  These metals are less reactive than the neighboring alkali metal. 3  These metals become more active as we go down the column.
