Compounds have been made from xenon and krypton, but not from other noble gases. Give a reason why. The elements in Group 18 on the periodic table are described as noble gases and usually do not form bonds. What is the cause of this?
Key Terms Atoms: Atoms are the smallest unit of matter. Atoms made of a nucleus of protons and neutrons and a cloud of electrons that orbits the nucleus. Molecules: Molecules are made of two or more atoms bonded together. Molecules can be made of atoms of the same element or from di...
Why it is important to have engine coolant as warming up the engine is better for its function? Calculate the density in grams per cubic centimeter of HfO_2, which has the CaF_2 crystal structure. Ionic radii are Hf^{4+}...
For native English speakers who do not speak Hindi or any dialect of Chinese learning these languages can can be quite the daunting thought. It is likely that these will be one of the two languages that may be potentially more important than English in the future due to their nascent and r...

It's our atmosphere that makes life on Earth possible. Not only does the air provide the oxygen we need to breath, but it also serves other important functions. One of those is that the atmosphere moderates our planet's temperature, reducing the extremes that occur on airless worlds. For ...
That's very important, so that you can start planning your strategies accordingly - ideally you'd like to know in advance if the Mayor is going to show up in the last round of play, so that you can try to set yourself up earlier in the game to capitalize on it! But then the ...
Inflammation inhibits PPARγ function The IKKβ/NF-κB (nuclear factor kappa B) pathway is a domi- nant inflammatory signaling pathway. The pathway has been under active investigation in the obesity field after IKKβ was found to induce insulin resistance in obese mice[37]. The serine kinase ...
Scientists also want a better understanding of trace gases in the air on Mars. Most scientifically tantalizing would be the detection of noble gases (such as neon, argon, and xenon), which are so nonreactive that they may have been around, unchanged in the atmosphere, since forming bi...
Dipped headlights are a trend that is seeing increasing popularity all over the world, for a variety of reasons. In this blog post, we will explore why we need check dip headlights and how to use them properly.
