  • Does any one know Mr. Vernier???

  • @xGrizzly17x yep what homeroom are u in?

  • @slangoshi 9-5 Mr. Verns sent me here

  • @xGrizzly17x 9-1 raf paterno

  • hehe plumbum

  • @SuperDabombz My students get a kick out of that also.

  • i wish you were my chem teacher, my teacher cannot explain things. she makes us take notes from the book basically...

  • BE MY TEACHER!!!

  • 6 People failed their exam and wish they watched these videos before hand.

  • How do we know the amount of valence electrons in transitional metals?

  • I am in a college Chem intro and i am so lost conversion with temps and mass etc . And we are going over this in class . Do you have anything on that PLEASE HELP ME WITH THIS Thank you .

  • Thank you so much! My teacher taught All 5 of your lessons in one class period...I was pretty confused. Thank you thank you!!!!

  • THANK YOU SO MUCH!!!!!! I"ll HAVE A TEST TOMORROW AND IM GONNA ACE IT!

  • @Itshardtopronuncius Let me know how you did. I'm sure you did amazing. Good luck with the rest of your studies.

    Mr.P

  • @Itshardtopronuncius LoL I have a test tomorrow and I'm trying to learn how to do this..

  • @Itshardtopronuncius Hope ya did great... though I would recommend studying.. Just an opinion though.

  • my teacher told me metals on the right of column 2B/12 should have the roman numerals as well.

  • @biggs95 Yes it's true but not all atoms to the right of this column are metals. I don't refer these metals because once you learn about electron configuration some of these metals are considered d-orbitals and some have p-orbitals. So there is a bigger picture that MY teachings build towards.

    Mr.P

  • @Papapodcasts the hitting noise is a bit off putting. things could be worse I suppose. Thank you for the help.

  • but how do we stil know which one to use

    ????????

  • @epcwnz thats what im saying

  • i understand how an element like oxygen would gain 2 electrons to have a -2 charge..What am getting confuse with, is how an element like fe has a +2 charge..

  • @zaqqy2010 The transition metals are a bit tougher to explain in 450 characters. You need to understand the concept of Quantum numbers of atoms (s,p,d.f-orbitals). Once you understand the quantum numbers can you understand how Fe can have a +2 or even a +3 charge. Look that up first. Good luck with your studies.

    Mr.P

  • @Mr.P, what do you mean by the reverse cross over rule, um for example top to bottem and bottem to top? :s Thank you.

  • @ApexpredatorCa1 the crossover rule is when you have the charges on top and then bring them down to "underneath" the element such as a subscript. The reverse crossover rule is where you have the subscript and you bring it to the top.

    Hope This Helps

  • I watched your video, but I don't really get the part of why you chose +2 for Iron instead of +3

  • @happybro1 You can choose any charge for any of the elements. In this case it is Iron. It is just for giving you an example. If he wanted to he could choose +3 and the equation would change a bit but it would still be correct.

  • @MrZomgzombies okay thanks so it's just the roman numerals that really tell you okay I just did my test anyways hope I did well :o

  • thank you! great video! are you writing this on a smart board?

  • @CuttingEdgeGuitar Thank you. Yes as a matter of fact, it is a Smartboard. It has it's own screen recorder software built in.

  • lol "BUT we've come across a problem!"

  • Thanks for watching and for the kind words for the other videos.  I wish you best of luck with your studies. Btw, what problem did you have?

    Mr.P

  • I didn't have a problem, that's a quote from your video haha and yeah good job with the videos

  • you are just great at getting it into my head. thank you. you are really such a help.

  • I'm glad that you found it helpful. Thanks for watching.

    Mr.P

  • Pb stands for Plumbum. lol

  • Hehehe, my students find that funny every time as well lol

    Mr.P

  • this video was very helpful with my understanding of transitional metals

    thanks

  • I still don't understand how I determine the number of valence charges that exist for each transitional element. How do I look at the periodic table and extract that information from it?

  • lol i know this is old but maybe someone else would like to know...

    you just look at the periodic table and below the symbol of the element it will give you two numbers. in the case of iron, it gives you 2, 3. those are the two valence charges mr.p used to get his answers.

    and because this demonstration occurs between non-metals and metals and chlorine is a non-metal, iron must be a metal. metals are positives, so the 2,3 are going to be positive charges.

  • OMG! My Chemistry teacher gave us a quiz on Friday and I got an 11/12 on it! And that was the highest in my class! Thanks to you Mr. P!

  • THAT IS AWESOME!! What a mark! I can't take all that credit, you did the hard part. All I did was make the videos. Keep up the great work. Ain't it amazing to get the top mark in your class. Hope it'll be added motivation for you throughout the course. Best of luck with the rest. Keep me posted.

    Mr.P

  • Man if you were my chemistry teacher in high school I think I would have done much better.

  • Thank you for the compliment and for watching my video. Best of luck with your studies.

    Mr.P

  • THANKS!

  • thank you for watching. Good luck with your studies.

    Mr. P
