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 is sort of the opposite to "Helium" because when you take in Helium it makes your voice go high and squeeky but once you take in Argon it makes your voice Low and manly! Hope this helped
Not normally.
At the same temperature, helium gas will move faster due to its lower atomic weight. Helium has an atomic weight of 4g/ mol, while argon has an atomic weight of 39.95g/ mol.
Oxygen
The noble gases, which are helium, neon, argon, krypton, xenon, and radon, have their outermost electron shells full.
hydrogen or heliumhydrogen or helium

They're nobile gases, meaning they have their outer valence electron shells filled and so practically no reactivity with other atoms. Helium has 2 electrons filling its valence shell whereas neon and argon have 8.
Argon and Helium are part of the noble gasses family.
No. Both helium and argon are chemically inert.
noble gases
argon
They form a mixture of argon and helium. Both argon and helium are noble gasses, meaning that the do not usually react and certainly will not react with one another.
Argon belongs to period 3. So it has 3 orbits with 2, 8 and 8 electrons.
It makes a helium-argon mixture - nothing more, nothing less.
No, not all noble gases have at least 3 electron shielding layers. The noble gas helium (He) has only two electron shielding layers, while the remaining noble gases (Neon, Argon, Krypton, Xenon, and Radon) have three or more electron shielding layers.
