Final answer:
The proper name for SF6 is sulfur hexafluoride, not sulfur tetrafluoride, making the statement false. 'Hexa' indicates six fluorine atoms present in the molecule.
Step-by-step explanation:
The proper name for SF6 is sulfur hexafluoride, not sulfur tetrafluoride. The prefix 'hexa' indicates that there are six fluorine atoms in the compound, as represented in SF6.
Sulfur hexafluoride has several applications, including being used as a tracer gas in ventilation systems, and as a spark suppressant in high-voltage electrical switchgear assemblies due to its inertness and non-toxicity. This makes option B (False) the correct answer.
