What is the atomic number for argon? Write the ground-state electron configuration of element W using the Noble gas shorthand. Why is hydrogen not a noble gas? What do the electron configurations for all the group 18 noble gases have in common?
Yes, while all Noble Gases are Inert Gases, some Inert Gases, like nitrogen, are not in Group 18. 7 Is it correct to say nitrogen is a Noble Gas? No, while nitrogen is often considered an inert gas under specific conditions, it's not a Noble Gas. 5 Are all Inert Gases safe for ...
NCERT solutions for CBSE and other state boards is a key requirement for students. Doubtnut helps with homework, doubts and solutions to all the questions. It has helped students get under AIR 100 in NEET & IIT JEE. Get PDF and video solutions of IIT-JEE Mains & Advanced previous year pap...
Substances change state when you cool them and that makes for a good criterion to define the coolest gas: The substance that reaches the lowest temperature in gas form. Cold is not a physical quantity; rather, cold is a qualitative description of the absence of heat. The state of total abs...
Which noble gas is the heaviest or most dense? Usually, the heaviest noble gas is considered to be radon, but some sources cite xenon or element 118 as the answer. Here's why. Noble gas elementsare mostly inert, so they tend not to form compounds. So, the easiest way to find the an...
What was the first noble gas compound and who prepared it? 02:59 Give the increasing order of abundance of the noble gases in air by vo... 02:02 Name the radioactive element among noble gas. 01:21 Which inert gas was discovered in semi atmosphere ? 01:11 What is the geometry of Xe...
We stopped for gas Oil An oil is any nonpolar chemical substance that is a viscous liquid at ambient temperatures and is both hydrophobic (does not mix with water, literally "water fearing") and lipophilic (mixes with other oils, literally "fat loving"). Oils have a high carbon and hydroge...
The description of thermal neutron scattering in a noble gas is discussed. It is shown that the commonly used Placzek's approach is not consistent with Turchin's formalism, which is nicely confirmed by Monte Carlo calculations. A proposal is made concerning a more adequate description of the ...
4. Remember that chemical reactions occur because atoms have valence electrons, which are electrons in their outer shell. When the outer shell is "unfilled" or the required number of electrons is not yet complete, the atom is more reactive. Noble gases have a full outer shell, meaning that ...
Similarly, hydrogen and oxygen, which are both gaseous elements can combine to form water, which is a liquid compound, not a gas, at room temperature. The process by which such combinations and transformations of elements into compounds take place is called achemical reaction. ...
