What Is An Atom And How Do We Know?

Ever wonder how we actually know that atoms exist? Here we'll learn what atoms are and exactly how scientists went about figuring all this out.

Note about the Nitrogen atom Image:

Each pixel in the image represents a reading from the scanning probe. The colors show us how high that particular part of the atom's electron cloud is compared to the substrate it's sitting on. Red is highest, blue is lowest. We are only seeing the outline of the electron cloud, not the nucleus.

Correction: In this video I state that Jabir ibn Hayyan was Arabian, but there is uncertainty about this among historians. He may have been Persian. Like many influential people of his time, his story is almost mythical, with multiple origins being found in historical writings.

Also, he never used a Bunsen burner (which is what I drew him using) that wasn't invented until 1856. Jabir likely burnt wood or other solid fuels to heat his reactions.

I used to think I disliked chemistry because it's "difficult", but the person breaking down the information in this video makes me enjoy it. wow. thanks!

[AnnieDiscepoli]

Thanks for helping this 60 year old who has decided to try to really understand the basics of chemistry. The best video by far!

As a high school science and chemistry teacher, I LOVE your videos and I'm so grateful! Keep making them!!!

I never understood chemistry in school. Thank you for breaking down the matter in such an elemental form.

I love the way you use the phrase "building blocks of chemistry" rather than the way I learned back in the 1950's "building blocks of matter". Yours is way more accurate. Teaching is the process of passing knowledge on in a way that is understandable. If the student doesn't understand it, it's not teaching, just babbling.

I don't think most people understand how absolutely amazing this discovery is... we're in a pixelated and vibrating universe the pixels (atoms) all vibrate at different frequencies...taking commands from the universal vibrating source.

Just sitting here reading a science book (for fun) that is beyond my comprehension. In looking up a few terms, I came across your absolutely wonderful video! So well produced, captivating and a perfect pace for the ADHD mind. I am excited to keep watching. Thanks for the great work!

I'm trying to help my children get a better understanding of what an atom is. This was the best breakdown of an atom I've ever seen. Wish I saw this when I took Chemistry class.

[fritzhaber]

I know most of the video and I'm still impressed with all these info and the way it was organised. Amazing job.

[bagdarcan]

finally i'm feeling like i'm coming closer to understanding the reality of atoms. you're awesome!

Teacher: PAY ATTENTION

Me: why r cookies so complicated...

[joeenglishtv]

You're thorough, you're crystal clear. You're conscientious even with the right pronunciation of foreign names - which is fantastic, you're simply great!
Carry on like this👍

I am a teacher of chemistry and I absolutely love the way you have put the video together. My students will like the animation, the simplified way you have described terms and still managing to convey the technical definitions. Well done!

[charlielitafire]

This isn’t the thing I wanted, but I want to keep watching...

I am an elementary school teacher, and I wish that all teachers were able to explain things this clearly and simply for people who want to learn. I sometimes even fail at doing this, complicating explanations, which causes students to either be bored, or fail to understand altogether. This is stated very clearly. 👍🏼

[akuhan]

um during quarantine I became such a science geek and started learning so much way ahead.. Chemistry Class is waiting for the boss arrival heehee

[emirtascioglu]

Who's here because of quarantine? 😞
