Scientists synthesize large borophene crystals Glowing dyes could store digital data for the long term. To call the noble gases lazy is unfair, even for an organic chemist. These elements work hard. Helium cools our magnetic resonance imaging scanners and nuclear magnetic resonance spectrometers.
Neon signs illuminate the best dive bars. Argon provides chemists with an inert atmosphere in their glove boxes. Krypton flashes help photographers capture images at high speed. Instead, one might describe the noble gases as aloof. But it is possible to wrestle reactivity from these elements, as the late chemist Neil Bartlett showed in , when he made the first noble-gas compound, Xe[PtF 6 ], by mixing xenon with platinum hexafluoride.
Making noble-gas compounds is not for the faint of heart, however. When compounds do form, the results are seldom practical: most noble-gas compounds are too fleeting or unstable to be useful.
But the few chemists who take on the challenge of coaxing reactivity from these recalcitrant elements say the true rewards are finding new insights into the nature of reactivity and chemical bonding. Gary J. Schrobilgen, a chemistry professor at McMaster University, has been making compounds with xenon and krypton for more than 40 years.
These, he points out, are the only noble gases that form stable compounds in quantities of a few milligrams or more—chemicals like XeF 2 , which can etch silicon, and KrF 2 , a strong but rarely used oxidizer. Skip to main content. Periodic Properties.
Search for:. The Noble Gases Group Learning Objective Identify the properties of the noble gases. Key Points Noble gases are colorless, odorless, tasteless, and nonflammable gases under standard conditions. In the periodic table, the noble gases are arranged according to their boiling point. Noble gases are widely used in different fields, from incandescent lighting to excimer lasers. Xenon is used as an anesthetic because of its high solubility in lipids, which makes it more potent than the usual nitrous oxide, and because it is readily eliminated from the body, which allows for faster recovery.

It's in the Father's Genes. Radon is a radioactive element. Radon gas is formed by decay of other radioactive elements and the concentration in the environment depends upon the types of rocks on which you live.
For example, the granite in Dartmoor contains small amounts of uranium that forms radon, which can accumulate in buildings and drinking water. This leads to an increased risk of cancer. This free course, The science of nuclear energy, will delve into the science behind nuclear power and explain what happens inside a nuclear reactor and what it means for an element to be radioactive. It will explore some of the risks of producing nuclear power and examine the arguments for and against including it in future energy planning as well as looking at other potential future solutions.
This free course, Ethics in science? You will conduct your own online research into an unethical scientist and finally look at some current moral dilemmas in science. Effective communication is essential in science, but do you ever wonder whether articles written about science in the news are thorough, unambiguous and objective?
Rigorous assessment is at the heart of good science. It will explore the ways in which scientific knowledge develops, undergoes peer review and is communicated. The second half of the course will focus more closely on a specific scientific topic — plastics — and give you a chance to practise these skills by considering the topic's social impact, building a glossary of unfamiliar terms, and evaluating relevant information sources.
