Noble Gas Compounds - Video Tutorials & Practice Problems

Noble Gas Compounds

When it comes to noble gas compounds among all group 88 elements, only xenon forms stable compounds. We're gonna say it reacts directly with fluorine and it forms fluorides. Now, if we take a look here, we have xenon as a gas, it's a noble gas and it reacts with some set number of fluorine gas molecules. Here, N can represent 12 or three and it produces xenon with some set number of fluorine atoms connected to it. X here could represent 24 or six. So just remember Xenon is an old gas that we focus on. It reacts directly with fluorine and it creates different types of xenon fluoride compounds with two fluorine, four fluorine or even up to six fluorides.

Noble Gas Compounds Example

In this example, it says a noble gas fluoride is a colorless crystalline solid at room temperature, which one of the following is the most likely formula of this compound. So here it's a fluoride. All these examples are fluorides. It exists as a crystalline solid at room temperature which indicates it's pretty stable. And we know that out of all the noble gasses, it's xenon that helps to make stable compounds and it makes stable compounds with fluorine. If we take a look, the only option that possesses xenon in the formula is option D. Here we have xenon tetra fluoride as this stable colorless crystalline solid find at room temperature.

Which of the following xenon compounds are too unstable to exist?

• A. XeF₂
• B. XeI₄
• C. XeF₄
• D. XeF₆
