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.
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.
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.
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.
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.
Niether. In 2015, the largest known atom belonged to ununoctium.
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.
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.
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.
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.
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.
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.
Yes, argon boils at a higher temperature than helium. Argon boils at -185.86°C whereas helium boils at -268.9°C.

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.
Argon has a higher mass number which means it has more particles in its nucleus than helium so I would go with argon.
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.
