The ionisation energy depends on the orbital from which the electron is removed and also the distance of the orbital from the nucleus.
In the case of Helium, the electron is removed from 1s orbital whereas in the case of argon it is from 3p orbital. As 1s is closer to the nucleus, the force of attraction experience by these electrons is higher and hence helium will have higher 1st ionisation energy.

What is Argon Ionization Energy?
Argon ionization energy is the amount of energy required to remove an electron from a neutral argon atom to produce a positively charged ion. In the case of argon, this energy is relatively high due to its stable electron configuration.
What is the ionization point of argon?
The ionization energy of argon is 15.76 eV, meaning it requires 15.76 electron volts of energy to remove an electron from an argon atom.
How much faster does helium move than argon?
Helium moves approximately three times faster than argon at the same temperature and pressure due to its lower molecular weight. This faster movement leads to helium having higher diffusion and thermal conductivity compared to argon.
Is helium and argon the same?
No, helium and argon are not the same. They are two different elements on the periodic table with different properties. Helium is a noble gas with the atomic number 2, while argon is also a noble gas but with the atomic number 18.
Which one has the largest atom helium or argon?
Niether. In 2015, the largest known atom belonged to ununoctium.
Why does helium have a higher ionization than argon?
Helium has a higher ionization energy than argon because helium has a smaller atomic size and a full valence shell, making it more stable and requiring more energy to remove an electron. Argon, being a larger atom with more electron shielding, has a lower ionization energy as the electrons are further away from the nucleus and experience less attraction.
Does argon or chlorine have a higher ionization energy?
Argon has a higher ionization energy than chlorine. This is because argon is a noble gas with a full valence shell, making it more stable and harder to remove an electron from compared to chlorine which is a halogen with one electron missing from a full octet.
Which elements on periodic table have the highest ionization energies?
The noble gases such as helium, neon, argon, and xenon typically have the highest ionization energies on the periodic table. This is because they have a full valence shell of electrons which makes it difficult to remove an electron.
What is Argon Ionization Energy?
Argon ionization energy is the amount of energy required to remove an electron from a neutral argon atom to produce a positively charged ion. In the case of argon, this energy is relatively high due to its stable electron configuration.
What is the ionization energy for Ar?
The first ionization energy for Argon (Ar) is approximately 15.8 electron volts (eV). This represents the energy required to remove one electron from a neutral Argon atom to form a positively charged Ar ion.
What is the ionization point of argon?
The ionization energy of argon is 15.76 eV, meaning it requires 15.76 electron volts of energy to remove an electron from an argon atom.
Does argon boil at a higher temperature than helium?
Yes, argon boils at a higher temperature than helium. Argon boils at -185.86°C whereas helium boils at -268.9°C.
What is lowest second ionization energy on argon calcium or potassium?
calcium
Argon is a stable gas with a very high ionization energy Which statement explains why?
Argon is a stable gas with a high ionization energy because it has a full outer electron shell, making it energetically unfavorable to lose or gain electrons. This stable configuration results in a high ionization energy, as a significant amount of energy is required to remove an electron from an atom of argon.
Which element has the largest atom Helium or argon?
Argon has a higher mass number which means it has more particles in its nucleus than helium so I would go with argon.
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.
Is helium more abundant than argon?
Argon, Ar. 0.93. Carbon dioxide, CO2. 0.033. Neon, Ne. 0.0018. Helium, He. 0.00052. Methane ... much higher than it is in air. ... Argon is the most abundant and most used of the noble gases.
