What is potassium-argon dating? Why is the periodic table arranged the way it is? Why did Dmitri Mendeleev create the periodic table? What is the molar mass of argon? Why are metalloids between metals and nonmetals? Why is the periodic table called periodic?

The noble gases are a group of elements that make up Group 0 on the Periodic Table of Elements. These elements include helium, neon, argon, krypton, xenon, and radon. Answer and Explanation: Elements that are chemically inert don't form compounds with other elements. This is because the el...
Why is fluorine a good choice to try to react with xenon? What are the typical characteristics of ionic compounds? Why do some ionic compounds dissociate in water and others do not? Why are the properties of sulfur, selenium, tellurium, and polonium significantly different from those of oxygen...
a geochemist at NASA’s Johnson Space Center in Houston, who is part of a group of over a dozen international experts that helps decide which samples the rover should collect. “Even scientists who don’t study Mars would be interested because it will shed light on how planets form ...
then, I felt that the brightness of the flash was “shockingly Awesome.” It could illuminate the whole street in one flash. Later I learned that it is called a “xenon flash”, brighter than an LED flash. Many, but they can’t be turned on continuously. They can only “flash by.”...
the Audi A8 luxury saloon in 2004, engineers and designers alike prefer to use light-emitting diodes (LEDs) when making modern cars. That’s because they use less power than Xenon units, give more freedom for styling the body parts, as they’re so ...
The objective was simple: NASA wanted to understand if we can crash into an asteroid to prevent such a calamity from also wiping out humans. So, as a proof of principle the spacecraft struck a little asteroid called Dimorphos, which is orbiting a larger asteroid, Didymos. ...
But with nuclear electric propulsion (NEP), the fission energy is instead used to ionize a gas. “The propellant expelled by a NEP system can be an inert gas, such as xenon or krypton, but iodine, lithium or hydrogen can be options depending on the type of electric thruster,” says ...
Out of all the elements known, noble gases such as helium (He), neon (Ne), argon (Ar), krypton (Kr) and xenon(Xe) are the most inert (unreactive) and are present in extremely low concentrations in our atmosphere. Therefore, they are grouped together in a
