Periodic Trends: Electronegativity, Ionization Energy, Atomic Radius - TUTOR HOTLINE

This video explains the major periodic table trends such as: electronegativity, ionization energy, electron affinity, atomic radius, ion size and metallic character. I also go over the exceptions to each trend and several periodic trends examples.

🙌 This was my go-to homework help when I was in school. Chegg Study is one of my favorites.

📚 I made the mistake of buying all of my textbooks, I wish I had the option of renting them. Thankfully you do, with Chegg Textbook Rentals.

💁‍♀️ HI I'M MELISSA MARIBEL
I help students pass Chemistry and Organic Chemistry. I used to struggle with this subject, so when I finally graduated with a bachelor's degree in Chemistry, I became a tutor so that you wouldn't have to struggle like I did. I know that with the right help, YOU CAN LEARN ANYTHING!

[hihello]

for some reason my chemistry teacher likes to complicate things
thank you for making it easier and understandable :)

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.

[kylie]

I’ve started a Melissa Maribel fan club in my chem class. You’re saving our lives and grades. THANK YOU THANK YOU THANK YOU

[kay-bgwr]

you’re the literal best chem teacher ever. you explain so much better than my teacher. thank you.

[christabellemacalino]

Watching this for my test tomorrow. I have learned from this more than from our class. Everything is now clearer to me. Thank you so much for your discussion!

[triumphcity]

Watching all of your videos before my Chem. final. Recommended this channel to every incoming freshman I know.

[Paytoon]

What am I even paying my chem professor anymore. Pretty sure this channel has taught me more in half the time I've spent in class. You're a lifesaver.

[a_bi_biscuit]

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.

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.

[QueenieDarling__]

wow I watched about 5 different videos about periodic trends and not one of them helped me... until I seen yours! you break it down so easy for me! thank you!

[MillionaireMello]

I just want to express a heartfelt THANK YOU. 💕
Going through your videos makes me feel like you are holding my hand and encouraging me not to quit and you dont even know me.

[yarelygalindo]

Literally I love you so much, I failed my first chemistry exam, and with your help, I got a 80 on my next one! <3

[blmandar]

Melissa, I really have no words to explain my gratitude to u right now. But if u were standing next to me right now I would hug u real tight and say "Thanks for saving my life, Superwoman."

[anoopmanakkalath]

I believe the electronegativity follows the below order. Ne > F > O > N >= Ar > C > Kr > Cl > S >= Xe > Se ~ I ~ Rn> other Helium's EN is very difficult to predict. Its should be less than that of oxygen.

[vandelium]

Thank you! I got a B+ on my quiz!! Better than any other quiz i’ve taken! Coming in clutch for my AP chem class 😭

[scarlett]

who else thinks they're going to fail their chem test tomorrow

[abhaj]

I have a chemistry quiz tmrw and this just literally saved my life thank you so much 🙏🙏🙏🙏

[molliek]

your videos are saving my life during quarantine right now! my chem teacher is posting your videos to help us learn, and it makes not having a teacher there so much easier. thank you!!

[suchpreetk]

I’m so glad I found you on YouTube, I don’t know how I would pass chemistry without your videos😭😭. I have a test on this tomorrow and I’m pretty confident now after watching you video. You are so helpful, thank you soooo muchhh!!!❤️

[yossefkouwatli]

I have been looking through my chemistry book for over 2 hours now, I asked the teacher, and searched everywhere on how to calculate the ionization energy and what are the exceptions, you were the only one who explained it very well and simply, I thank you so much.
btw if you were interested the question I had, it was:
In which of the following does the second element have a lower first ionisation energy than the first element?
a)S. O
b)Li. Be
c)Mg. Al
d)Si. C
and from what I understood from the video the answer should be c). please correct me if I am wrong
thank you.
