In King Kong, the island is never mentioned by name and is located at approximately 12Â°S 78Â°E / 12Â°S 78Â°E / -12; 78 â somewhere off the coast of Sumatra, Indonesia. There is a distinctive rocky knoll in the center of the island that is shaped like a human skull, which is referred to as Skull Mountain.
In order to be able to determine how many lone pairs are present in a carbon dioxide molecule, you need to draw its Lewis structure. Carbon dioxide has a total of 16 valence electrons, 4 from carbon and 6 from each of the two oxygen atoms. In order to give the central carbon atom a complete octet, you need to form two double bonds with the two oxygen atoms. These bonds will account for 8 of the 16 valence electrons the molecule has.
Carbon will then have five valence electrons (its four and the one its sharing with fluorine). Covalently sharing two electrons is also known as a single bond.. Carbon will have to form four single bonds with four different fluorine atoms to fill its octet. The result is CF4 or carbon tetrafluoride.
