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.
The main-group metals usually form charges that are the same as their group number: that is, the Group 1A metals such as sodium and potassium form +1 charges, the Group 2A metals such as magnesium and calcium form 2+ charges, and the Group 3A metals such as aluminum form 3+ charges.
