Why is helium considered a noble gas? Noble Gas: The elements found on the right side of the periodic table i.e group 18 is known as a noble gas. Noble gases are non-reactive. The outer most shell of the noble gas is full. They have high ionization energy. Examples of noble gases ...
Why is helium considered a noble gas? Why does the concept of antisymmetric wavefunctions not need to be considered for the hydrogen atom? Explain why Zr4+ ion exists? Explain John Dalton's experiment that led to his atomic theory.
Inert means non-reactive. Inert gases do not react with fluorine and oxygen except under exceptional conditions that do not occure naturally on the Earth. Wiki User ∙9yago This answer is: More answers AnswerBot ∙6moago Copy Inert gases, such as helium, neon, and argon, typically do ...
Helium isn't the kind of element that makes friends easily. Being so light and non-reactive, there's little to stop the gas from diffusing out of exposed rocks into the atmosphere and drifting off into space. That makes helium a surprisingly rare material on the planet's surface. Yet jus...
(43) What is the reason behind the so high cell emf (2.0 V) of lead acid battery? (44) Which is the most reactive metal in the earth? (45) Why is cesium (Cs) more reactive than francium (Fr)? (46) How can we explain the difference in colours: tin dioxide (SnO2, white) ...
Non-Reactive Gases If you take a close look at the periodic table, you'll notice a very special column all the way on the right hand side. In this column are some very unique elements called the noble gases. These are helium, neon, argon, krypton, xenon, and radon. All of the noble...
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...
Mesothelioma is a rare form of cancer that develops as a result of asbestos exposure in the mesothelium, which the protective lining that covers most of your body’s internal organs. Unfortunately, the risk of getting mesothelioma after exposure to asbestos is lifelong. However, unlike lung canc...
Atoms tend to be reactive when their valence shell (or outermost shell) is incomplete. To achieve a complete state or a closed shell, an atom does one of the 3 things: lose, gain, or share its electrons with other atoms. An atom isn’t as simple as we think it is—a nucleus with...
