What is the element krypton?Reactive and Inert Elements:At one point in history, it was believed that the noble gases, also called the inert gases, did not react with anything. However, the element fluorine is so highly reactive that it actually can react with these elements. An elements ...
Third Group Element: The element, scandium, is named after the Latin word for Scandinavia,Scandia.This element was discovered in 1879. It's found in Group 3 in the periodic table and has a chemical symbol of Sc. Answer and Explanation:1 ...
Krypton is a gaseous chemical element that exists in concentrations of about one part per million in the Earth's atmosphere. Since it exists in low concentrations, it is difficult and expensive to extract, making it rather expensive when it reaches the market. Its most common use is in lighti...
are classified by the number of protons in the nucleus of the atom. However, there is no set rule for how many neutrons can be in the atom's nucleus. Because this number can vary, we classify the different, naturally occurring, variations of neutron quantities as isotopes of the element....

the seventh element of the periodic table between carbon and oxygen is nitrogen. it’s an important part of amino acids. around eighty per cent of the earth’s atmosphere comprises nitrogen gas. it has no colour, mostly diatomic non-metal gas which is odourless and colourless in nature. ...

Until recently, young 16-year-old Kal-El's entire life has been about training and preparing to be Supreme Ruler of Krypton. But when he learns his planet is doomed, he faces a new journey -- not just to be Krypton's sole survivor on a distant planet called Earth, but also to find...
An atom is the smallest possible amount of a chemical element—so an atom of gold is the smallest amount of gold you can possibly have. By small, I really do mean absolutely, nanoscopically tiny: a single atom is hundreds of thousands of times thinner than a human hair, so you have ...
Each of the so-called noble gases — helium, neon, argon, krypton, xenon, and radon— is naturally a monatomic gas at standard temperature and pressure. The term has a somewhat different meaning when it comes to ions, since monatomic ions are made up of only one element, but each such ...
