What is argon? February 4, 2015,Nathan,Comment Closed Argon is the most abundant noble gas present in the Earth. About 1% of the Earth’s atmosphere is composed of Argon. In terms of behavior, Argon is considered very stable but not totally inert. This… ...
The average atomic mass of oxygen is 15.999 AMU. This value rounds to 16, which indicates that oxygen-16 is the most abundant isotope of oxygen... Learn more about this topic: Average Atomic Mass | Definition, Formula & Calculation from...
Here's how to remember the difference. If you join two different chemical elements together, you can often make a completely new substance. Glue two atoms of hydrogen to an atom of oxygen and you'll make a single molecule of water. Water is a compound (because it's two different ...
Atom is considered as the building block of matter and on the basis of the type of atom, a matter can be made distinguishable with others. On the basis of the orientation of atom in a matter, it can be named as solid, liquid and gas.Answer and Explanation: In the gaseous state of t...
What is the most common isotope of argon? Isotopes Explained: Elements 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...

What is the atomic number of uranium-238? What is the atomic number for argon? What is the atomic number for boron? What is the atomic number of ruthenium? What is the atomic number of protactinium? What is the atomic number of flerovium?
This occurs mostly with gases, and all elements can achieve this single-atom state at sufficiently high temperatures. 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 ...

An atom of Krypton in the gas phase, for example, gives off energy when it gains an electron to form an ion of Krypton. Kr + e–→ Kr–– ∆H = Affinity = — kJ/mol To use electron affinities properly, it is essential to keep track of signs. When an electron is added to a ...
