[@awesomelife4136]

Yaa

[@erikacorona7413]

She forgot to mention something very important regarding the Ionization Energy part; Another exception other than the two she named is that the NOBLE GASES are going to have the HIGHEST ionization energy since they are so stable it is going to require the most energy to remove an electron.

[@harmie1743]

Do the noble gases follow the same vertical trend (higher row the noble gas is, higher IE compared to lower noble gases?

[@erikacorona7413]

@@harmie1743 No, because now another component has to be taken into consideration; orbit size. The bigger the orbit the less energy it’ll need to removed an electron since it’s so far away from the nucleus now and the smaller it is the harder it is to remove an electron since it’s closer to the nucleus. So when you are going down the noble gases periodically they get bigger and bigger thus less IE. Therefor the most IE will reside with the noble gas of Helium.

[@a_bi_biscuit7448]

This whole Channel is a life saver. My chem teacher is not the best so I never understand anything unless I ask a billion questions. This video helped me a lot with my homework because my teacher told us to figure it out basically.

[@terrencesmith1146]

18:12 - one way I can recognize which is larger is because Br has 35 protons while Kr has 36 protons, the 35 protons in the Br nucleus is going to have less of a pull to the 36 electrons compared to the pull of Kr's 36 protons so Br will be larger. Understanding this requires understanding the shielding effect, but for me it's helpful to know the why behind anions being larger.

Thank you so much for the lesson, understood it like a gem. I'd like to add a suggestion regarding the questions: I think you should add complex comprehensive questions as well or more of a diversity because there was really two distinct structural questions. One, that was about this element vs. this element, two, was about ordering elements in ascending order due to their properties. I reckon if you added perhaps two other indefinite structural questions, it would challenge the understanding of the viewer. Anyway, thank you :) Your videos are very helpful in terms of learning the content. I will start chemistry this year with the knowledge you gave to me, which in that, is powerful.

I think all tutors should be teachers because tutors actually WANT to help a student understand their work! “Regular teachers” just kinda stand at the front of the classroom or lecture hall and blubber about whatever, and don’t seem to care if students understand anything or not because it’s “not their job to learn because they’re not the student” (lol okay what?)
