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 short answer is that most ionic bonds are formed between a metal and a non-metal, like NaCl. Covalent bonds form between non-metals like hydrogen, carbon, oxygen, and nitrogen like H 2 O or CO 2. The long answer has to do with electronegativity, the pulling power or attraction for electrons in a chemical bond.
