Helium has 2 electrons in the 1s orbital, meaning that these electrons are as close to the nucleus as possible. The nucleus has a positive charge, pulling these negative electrons very tightly. It takes a lot of energy to break this attraction. Having 2 electrons in the 1s orbital also means that it is very stable. Other elements with full outer shells or with electrons in other orbitals having a smaller first ionisation energy than Helium. This is because the electrons in previous orbitals shield the valence (outer) electrons, so the charge of the nucleus isn't felt as much, and is therefore easier to break the attraction.
Noble gases have high ionization energies due to their stable electron configurations and full outer electron shells. This makes it difficult to remove an electron from them compared to other elements. The ionization energy generally increases from helium to radon within the noble gas group due to increasing nuclear charge.
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.
ionisation energy order for gr 14 is c>si>ge>sn<pb
The element with the largest ionization energy in its period is typically found in the top right corner of the periodic table. This is because elements in this region have the highest effective nuclear charge, making it harder to remove an electron. In general, elements like helium, neon, and fluorine tend to have the highest ionization energies in their respective periods.
it would have to lose an electron to become an ion as it allredy has a full outershell, for every electron lost the He will gain a charge of +1, but this would be very difficult to obtain as its ionisation energy is very high, in the periodic table ionisation enerygy goes up as you go across the period (from left to right the amount of nuclear charge increases) and it also goes up as you go up a group (as you go up a group the amount of inner sheilding ans distance between outer electron and nucleus decreses, increasing nuclear charge and decreasing shielding and distance all increase ionisation energy) and He is right in the top right corner, Helium has the highest first ionisation energy (ionisation energy is the amount of energy needed to remove one electron from each atom in 1 mole of an element in an gaseous state). the charge of its ion will completely depend on how many electrons it has lost.
Noble gases have high ionization energies due to their stable electron configurations and full outer electron shells. This makes it difficult to remove an electron from them compared to other elements. The ionization energy generally increases from helium to radon within the noble gas group due to increasing nuclear charge.
Helium has the greatest ionization energy. Its electron is being removed from the principal shell closest to the nucleus. It has a greater I.E. than hydrogen does because the electron is being pulled away from a greater nuclear charge.
Helium has the highest ionisation energy of all the elements. It takes 23779kJ to remove only one electron from 1 mol or 4.003g of helium. Trying to ionise 1 gram or 6.193L of Helium is the same as boiling around 75 850L of water Helium has a very high ionisation energy because its atomic radius is very small which causes the force of attractiion between the nucleus and the electrons to be very strong.
Helium has the highest ionization potential in the periodic table due to its stable electron configuration with a full valence shell of electrons. This makes it difficult to remove an electron from a helium atom, resulting in a high ionization energy.
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.
