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.
Acids, alkalis and neutralisation - higher. When atoms or groups of atoms lose or gain electrons, charged particles called ions are formed. Ions can be either positively or negatively charged. For the Higher Tier, you need to know which ions are produced by acids, and which are produced by alkalis. You will also need to know the ionic equation for neutralisation.
