  • this is a good way to explain it but perhaps you should consider giving the real answer with the examples. so it takes more inoization energy to remove electrons from left to right ok. why??? as you go from left to right, protons increases. protons attract electrons, holding them together more tightly. just a suggestion. no offence or negativity intended.

  • @ftart yup, you're right. that's an important concept for sure. but it's always a delicate balance between telling part of the story and giving too much information. as a teacher, i find that if you give too much information at once, the whole concept is lost. if you were in my class, the next day after this lesson, i'd say, "now why do the atoms get smaller?" and we'd go from there. if you're interested in teaching (i hope you are!) a vital thing to think about is: "what can i leave out?"

  • very simply, metals lose their electrons to become positively charged cations. while on the other hand, non-metals gain electrons to become more negatively charges anions

  • this is so helpful thank you

  • This helped me ACE my final, i got my 3.8 GPA!!!!!!! you are a great teacher. Keep it up :)

  • OMG it took this guy 9 mins to teach this to me and its been over a week && i still cnt learn this from my teacher THANK YOU SOOO MUCH

  • I cannot express my gratitude for this video! It was so helpful I wish you were my chemistry professor. That is the most accurate explanation and analogy I have ever had! Thanks again!

  • oh my gosh, that was the best chemistry lesson I have ever had. where do you get all the energy to add the hand motions and fun analogies. I have to say though, I got a bit confused by the two different anologies you had at work. The old lady/thug analogy suggests that bigger atoms (thugs) will be hard to steal from. However, the dangling purse analogy tells us that bigger atoms (danglers) are easier to steal from. I would maybe just use the second anology if it were me.

  • I figure its an all around bad situation if the tough guy is carrying a purse.

  • what do i do if my chem teacher makes me fall asleep??

  • bless you oh my god

    so helpful, thank you so much!

  • i cannot pay attention, as he talks i just keep imagining he is a grown up justin bieber
