Science Facts Thursday: The Atomic Structure

Don't trust atoms, they make up everything!

It's science facts Thursday! A slightly delayed one, since we have been enjoying a little break and have been on lots of mini adventures, including a trip to the Museum of Science and Industry to see an exhibition on brains! More on that another time..

..This week we look at the structure of an atom. What is an atom? Everything is made up of atoms, everything, including your breakfast cereal to the smell of roses. They are super tiny too, so super tiny that in a single grain of sand there is close to 78 quintillion! (That's 78, 000, 000, 000, 000, 000, 000)

So what does an atom look like?

Not to scale.

The diagram above shows the structure of an atom. We used Carbon as an example. Carbon has 6 protons,  6 neutrons and 6 electrons with 2 shells.
The number of shells an atom has depends on the number of electrons.

This is where is gets complex. There are things called isotopes. These are variations of atoms of an element. For example, the diagram above shows a regular carbon atom, an isotope of carbon is 'carbon 14' which has two extra neutrons! This carbon atom is unstable and is radioactive! Think of it as the naughty identical twin.

Protons and Neutrons are best buds, and hang out in the nucleus.

The positive charge of the protons and the negative charge of the electrons in an atom keep everything stuck together by attracting one another. They also cancel out the electrical charge making an atom neutral .

Next week we look at the Kinetic Theory! In the meantime enjoy this song about atoms. ♥


  1. Oh my word this is simply fabulous!

  2. thank you cute way of helping with homework lol :D

  3. Hey there, just a quick one, protons are positively charged.
    Great site and drawings though!

  4. protons are positively charged stupids

  5. I love your work! Is there more than where you left of in 2014? I have a kid who is going to flip tomorrow when de sees this page!! :)

    1. Hello! Thank you :)

      This was just a hobby of mine, I got a little behind with my weekly posts to the point I totally forgot about it. I'm planning on bringing it back in the next few weeks!

      I also illustrate other things, and make stuff, you can check it out at:




      Thanks for your comment :D

    2. Thank you for responding! You have no idea how happy you made my 5 yr old little boy!! btw I fixed the proton/negative thing today. I hope you don't mind. :/

  7. The font is called peach milk just an fyi

  8. Protons are positive not negative :)

  9. Actually, I am facing some difficulties to understand the meaning of the blog. If you have any short video film related to your blog, then I would request you to share here. It would be great help.ฉีด ฟิลเลอร์

  10. This is really nice to read content of this blog. A is very extensive and vast knowledgeable platform has been given by this blog. I really appreciate this blog to has such kind of educational knowledge.
