5. Because of their properties, noble gases have many important applications. They are widely used in medicine and industries. For instance, liquid Helium is used for superconducting magnets(磁体). These magnets are very important in physics and medicine. When a doctor suspects that a person’s...
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 reactivity is highly dependent on its natural stability crea...
Noble gasesare elements that do not have valence electrons and, therefore, do not need to form covalent bonds to become stable. Some may consider them a molecule composed of only a single atom. In salts and ionic bonds, there are not conventional covalent bonds, so they are not considered ...
A plasma, first identified in 1879, consists of highly charged particles with high kinetic energy. Typically, plasmas are gases that are ionized at high temperatures. Examples of these gases include helium, neon, argon, krypton, xenon and radon -- all of which are noble gases and can be ion...
Chapter 7/ Lesson 9 84K In this lesson: understand what the noble gas elements are, where they are found on the periodic table, and why the noble gases are stable. Related to this Question Explore our homework questions and answers library ...
One of the six noble gases, Helium, is widely used in the cryogenics processing industry. It has specific properties that make it suitable for cryogenics.
paragraph 4() A. what is theperiodic table B. What are noblegases C. What causes the lowchemical reactivity of noble gases D. How were noblegases discovered E. How were noblegases understood in the past F. what are theapplications of noble gasesA
noble gases are completely inert, but it turns out that the laws of space are different from those of our planet. Here, we can only bind noble gases in laboratories, but in outer space, those chemical reactions happen naturally, and these so-called "impossible elements" may provide vital ...
Elements that have names ending with -inebelong to a group of elements called halogens. Halogens are extremely reactive and readily form compounds. Element names ending with -onare noble gases, which are inert or nonreactive gases at room temperature. ...
At the conclusion, the noble captain beaches the Colorado, then Navy fighters blow her up to prevent the ship from falling into Chinese hands. Blowing up a submarine with 288 hydrogen bombs aboard should not cause a nuclear explosion -- such warheads are elaborately trigger-locked. But highly ...
