Sulfur is an exception to the octet rule and can possess less than eight electrons in a covalent compound. true false

Sulfur is an exception to the octet rule because it can have an expanded valence shell that holds more than 8 electrons. Common examples are sulfur tetrafluoride which has 10 valence electrons and sulfur hexafluoride which has 12 valence electrons.

However, there are no sulfur compounds with less than 8 valence electrons. So, the answer is false.
