Why is electron gain enthalpy of inert gases positive?
Inert gases are the most stable ones, so if we try to add another electron, the stable electronic configuration is disturbed. So, we have supply energy for this process. Hence, electron gain enthalpy is positive.
Name the elements with highest ionisation enthalpy?
The elements with the highest ionization enthalpy are helium, neon, and argon. These noble gases have full valence electron shells and are very stable, making it difficult to remove an electron from them.
Why the value of electron affinity is positive for noble gases?
Noble gases have completely filled orbitals / energy levels. They generally have 8 valence electrons (helium has only 2) and have stable electronic configuration. They will not accept any more electrons and hence they have positive electron affinity.
Does a positive Potassium ion have noble gas stability?
No, a positive Potassium ion does not have noble gas stability. Noble gases have a full outer electron shell, but a positive Potassium ion (K+) has lost one electron and does not have a full outer shell.
Which Noble Gases has the largest atomic radius?
Radon has the largest atomic radius among the noble gases due to the increased number of electron shells, causing the atoms to be larger in size.

The elements with the highest ionization enthalpy are helium, neon, and argon. These noble gases have full valence electron shells and are very stable, making it difficult to remove an electron from them.
Why are electron affinity values for the noble gases endothermic?
Electron affinity values for noble gases are endothermic because these elements have stable electron configurations and do not readily accept additional electrons. This makes it energetically unfavorable for them to gain an extra electron, resulting in a positive electron affinity value.
Why the value of electron affinity is positive for noble gases?
Noble gases have completely filled orbitals / energy levels. They generally have 8 valence electrons (helium has only 2) and have stable electronic configuration. They will not accept any more electrons and hence they have positive electron affinity.

No, a positive Potassium ion does not have noble gas stability. Noble gases have a full outer electron shell, but a positive Potassium ion (K+) has lost one electron and does not have a full outer shell.
Which element would most likely have a positive electron affinity between Na Al Rb and Ar?
Chlorine (Cl) would most likely have a positive electron affinity. Typically, elements with high electron affinities are found on the right side of the periodic table, closer to the noble gases. Among the choices given, Argon (Ar) is a noble gas and has a positive electron affinity.
Which Noble Gases has the largest atomic radius?
Radon has the largest atomic radius among the noble gases due to the increased number of electron shells, causing the atoms to be larger in size.
What group of elements give off the most energy when they gain an electrons?
Group 8A, the noble gases because they have high electron affinity.
What is the pressure- enthalpy diagram for refregerant gases in refregeration industries?
mX+4# n4 k4u?
How can metal elements achieve a stable electron-shell structure like those of the noble gases?
Metal atoms achieve a stable electron shell structure by losing electrons to form positive ions. This electron loss allows them to attain a full outer electron shell like the noble gases. This process of losing electrons is known as metal atoms undergoing oxidation.
Can noble gases have either a positive or a negative charge?
None of them have a negative charge. Or a positive charge. They can be ionized by high voltages, as (for example) neon is in a neon sign. However, neon doesn't have a monopoly on that, all of them exhibit the same behavior.
Why are the noble gases non reactant?
Noble gases have atoms with the valence electron shell filled.
