The Periodic Table of the Elements in Chemistry - [1-2-12]

In this lesson, you will learn about the periodic table and how it is used in chemistry. We will focus on how the periodic table is organized by atomic number, and discuss how properties of elements are periodic in nature throughout the table due to the electrons in the outer shells of the atoms. We will also discuss atomic mass and valence electrons, including predicting when an atom will gain or lose an electron in a chemical reaction..

Failed Chemistry in H.S. (1960's) - - my teacher was terrible. Later became a physician, took lots of Chemistry to get there. Now I watch your videos for the entertainment value, lamenting the miserable experiences with instructors who have zero communication skills. Many thanks!

Sir, I am French leaving in Spain. You are a great teacher. In spite my poor English knowledges I understood every things you said. But most important whitn the pleasure to learn not feeling desplease whatsoever. Lot of thanks and respect. Peter

I never understood periodic table since my grade 10, but with dis, periodic table is now easy for me. Thanks sir Jason Gibson you're indeed the greatest of all teachers (GOAT). Remain blessed.

Sir, Another fantastic lesson. You are a superb teacher and I understand so much more from your lessons than i ever did in my education years. I cant thank you enough its bringing my interest back in science.

Where were u and youtube when I did chemistry...41 yrs now . U made stuff so clearer. Thanks sir

[minkone]

Jason, thank you for breaking this complex topic down for people like me, who felt they had hit a wall at school back in chemistry class. Your delivery is brilliant and the periodic table finally makes sense to me.

I’m 63 years old. I don’t say this lightly - Jason is hands down the greatest math and science teacher I’ve ever come across.

If I had had an explanation on the PT like this one, It would would have made sense to me n I would have realized how brilliantly it was assembled.
You Rock !

[thedinneris]

This was sooo good, good ! After 40 years of college - such a beautiful refresher !

Goodness this Gentle man is areal communicator in every aspect that he touches. He has been my son's teacher for the last two months before he sat his examinations this very month running 🎽

Best explanation I've heard. We've always been told how great the table was arranged, but I never really knew why, or how it was so great. I just didn't see what the elements were "doing" other than if you add one proton after H you put it in another box and then add another one, you add one more box and so on until you got boxes 1-118. So what? NOW I see a method to the madness, and how they blend and how their relative positions are related and how they move to certain characteristics. Using the nobles as the basis for all the other elements to reach stability was really cool. Using groups as valences or how many electrons one group needed or wanted to give up to another group was new to me (it's been decades since I was in college). Thanx for the lesson.

Thank you sir, everytime when i am watching you the way you break down complex problems in both Physics and Chemistry, you turn to awaken my passion for education.

[yordanmishev]

Extremely educational and well made to understand easily! This is legacy!

[markgraham]

I’m visiting after 20+ years of being out of chemistry. Still have an interest and I see how passionate you are. I’m very similar when teaching friends something. I appreciate that in you. Thanks a lot for the lessons.

[charoperticone]

You are a profesor out of this world!! Thank you so much! I learn a lot and of course I need it to review again. ❤❤❤❤

[gorillagaming]

Every video that I watch just brings enlightenment, thank you Jason truly.

So, in short, TIG welding needs pure argon to protect the tungsten electrode, and MIG welding works best on a 75%/25% argon/carbon dioxide mix to get good weld penetration and flow. However The normal gas for TIG welding is argon (Ar). Helium (He) can be added to increase penetration and fluidity of the weld pool. Argon or argon/helium mixtures can be used for welding all grades. In some cases, nitrogen (N2) and/or hydrogen (H2) can be added to achieve special properties.

I really appreciate the way you capture the essence and joy of chemistry. I have one question. Hydrogen has the ability to take or receive an electron, and if you consider there are only 2 elements using the first electron energy level, it seems like it fits the pattern for the top step of the metalloids. Any thoughts?

[tidbit]

You know what’s crazy, I’ve been trying to learn general chem prior to when I need the course and upon a few days in I had all of these EXACT questions that others kind of just glossed over while going in order of a syllabus. Thank you so much!!! A true blessing to future scientists 🖤

Still my favourite teacher on internet
