What is the definition of inert gas in chemistry?
An inert gas is a gas which does not undergo chemical reactions under a set of given conditions. The noble gases often do not react with many substances, and were historically referred to as the inert gases. example argon, neon(at normal conditions)
What is the electronic configuration of noble gases or inert gases?
A noble gas configuration of an atom consists of the elemental symbol of the last noble gas prior to that atom, followed by the configuration of the remaining electrons. So for sodium, we make the substitution of [Ne] for the 1s22s22p6 part of the configuration. Sodium’s noble gas configuration becomes [Ne]3s1.
What is the difference between electron configuration and noble gas configuration?
An electron configuration is the sequence of electrons that are present in an atom. The key difference between noble gas configuration and electron configuration is that noble gas configuration has only electron pairs whereas an electron configuration can have both paired and unpaired electrons.
What is inert gas configuration and pseudo inert gas configuration?
Pseudo ā inert gas configuration means having 18 electron instead of 8 electrons in (nā1) shell electronic configuration after gaining or loosing electron. The ions of certain elements are stable as they have a complete valence shell but do not have the configuration of a noble gas .
What are inert gases examples?
Group 8A (or VIIIA) of the periodic table are the noble gases or inert gases: helium (He), neon (Ne), argon (Ar), krypton (Kr), xenon (Xe), and radon (Rn). The name comes from the fact that these elements are virtually unreactive towards other elements or compounds.
Why noble gases are called inert gases?
Noble gases belong to the 18th group of the periodic table. They include helium, neon, argon, krypton, xenon and radon. They are called inert gases because they are stable and non-reactive.
How does noble gas configuration help in the concept of bonding formation?
Elements forming covalent compounds achieve noble gas configuration by sharing electrons within the atoms, unlike ionic compounds which achieve the noble gas configuration either by gaining or losing electrons from the outermost electron shell.
What is pseudo inert gas configuration with example?
Certain elements, ions are stable because their valence shells are complete, but they do not have the configuration of a noble gas. This is referred to as a pseudo noble gas arrangement. Example of pseudo inert gas configuration: Cu2+ Its outer shell has 18 electrons.
Why are inert gases called so?
What are the properties of inert gases?
Following are several Physical Properties of inert gasses:
- Atomic Radii (Atomic size) As we move down the group from helium to radon the atomic size of Noble Gasses keeps on increasing.
- Boiling and Melting Points.
- Density.
- Ionization Energy.
- Ionization Potential.
- Electrical and Heat Conductivity.
How many inert gases are there?
six
There are six primary inert gases which include helium, neon, krypton, argon, xenon, and radon. Carbon dioxide and nitrogen gas are also considered to be inert gases, but they are compounds rather than elemental gases. Some inert gases can react with other atoms in certain conditions.
Why noble gas configuration is stable?
Noble gases contain even number of electron in orbital or they contain completely filled atomic orbitals hence they do not take part in chemical reactions and their electronic configuration is stable.
What are the examples of inert gases?
Helium, nitrogen, neon, argon, krypton, xenon, and radon are inert gases.
Why do inert gases have zero electron affinity?
Inert gases in the group 18 , have stable fully filled outermost (valence) shells. Therefore, their affinity to add electrons is zero.
Why are noble gases chemically inert?
Noble gases are chemically inert because they have completely filled orbitals in the valence shell which leads to stable electronic configuration.
What is the electron affinity of inert gases?
Inert gases in group 18, have stable fully filled outermost (valence) shell. Therefore, their affinity to add electron is zero.
