Great job! You are absolutely correct! The group ionization energy decreases because the number of shells increases and the atomic size increases. The period ionization energy increases because the shell remains the same and the nuclear charge increases.
In Q 2 Why did sir, fid not condider the 1s² 2s² to be the one with highest ionization enthalpy ? It is fully filled. Where else 1s²2s²2p³ is half filled. Anybody please explain.
22:51 Sir I have a doubt that if I solve this question according to your logic then why we did not take (i) 1s²2s² part as the one with higher first ionization enthalpy but if I convert the electronic configuration of part (i) to an element name then it would be Be and the name of the element (iv) in part would be N. So, now I can say that N has higher first ionization enthalpy than Be.
46:40 doubt........❤ Sir is question mein I and I anion mein se anion ka size bada hoga..... Therefore uski ionization energy kam hogi... So why we have seen electronic configuration here Please answer me❤❤❤❤😊😊😊😊😊
In groups ionization energy decreases because the atomic size of atom get increase and nuclear charge remains same so it's easy to remove the electron from its valence shell hence low ionization energy required 26:11
The ionization energy increase in periods because atomic size remains same and nuclear charge increase so the required energy for removal of electron will be high 26:11
Thank you for your question! You are correct that the ionization energy is inversely proportional to the size of the atom. However, the reason that the I^- ion has more ionization energy than the I atom is because the I^- ion has more electrons than the I atom. When there are more electrons, the atom is more stable and therefore has more ionization energy.

Thank you for your question! The reason that Fluorine (F) has a higher ionization energy than Nitrogen (N) is because Fluorine has a smaller atomic radius. This means that the electrons in a Fluorine atom are closer to the nucleus than the electrons in a Nitrogen atom, and therefore require more energy to be removed.

Half filled and fully filled are extra stable because they have symmetrically energetic and have high exchange energy 10:34
Group ionization energy decrease -Reason ( no.of shells increases, atomic size increases) 2. Period ionization energy increases-reason ( shell remains same, nuclear charge increases)
Great job! You are absolutely correct! The group ionization energy decreases because the number of shells increases and the atomic size increases. The period ionization energy increases because the shell remains the same and the nuclear charge increases.

15:36 sir why 4.) Required more ionisation energy if we see in 1.) Option Is 1.) 1s² 2s² which more stable bcoz smaller radius size and s² is stable
Did you get the answer?
Same doubt .
Sir I have a doubt..In F,N,O- N is half filled then N will have the greatest ionization then why the answer is F?
Thank you for your question! The reason that Fluorine (F) has a higher ionization energy than Nitrogen (N) is because Fluorine has a smaller atomic radius. This means that the electrons in a Fluorine atom are closer to the nucleus than the electrons in a Nitrogen atom, and therefore require more energy to be removed.
Thank you sir..
