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.
As a result, they can also form covalent bonds particularly with large anions that can be polarized easily. Non-metals can gain electrons completely to give anions and hence can form ionic bonds. But they can also share electron pairs with other non-metal atoms and can form covalent bonds too. Simply, metals lose electrons and can form only ionic bonds. Metalloids and non-metals not only form covalent bonds by sharing, but can form ionic bonds either by losing or gaining electrons. Note: However, transition metals tend to form coordinate covalent bonds due to relatively smaller sizes.
