What is the correct name for Col_(2) A Cobalt Difluoride B Cobalt (II) Fluoride C Cobalt (1) Fluoride D Cobalt Fluoride

The correct name for $Col_{2}$ is B. Cobalt (II) Fluoride.<br /><br />In this compound, the cobalt ion has an oxidation state of +2, which is indicated by the Roman numeral II in the name. The fluoride ion has a charge of -1, so two fluoride ions are needed to balance the +2 charge of the cobalt ion. Therefore, the correct name for $Col_{2}$ is Cobalt (II) Fluoride.
