Chemistry is Fascinating!

Did you know that an atom is about 99.999999999% EMPTY space?

It was calculated, by the Institute of Physics in the UK, that if you removed the empty space of the atoms of ALL HUMAN BEINGS, you could fit the ENTIRE HUMAN RACE inside of a SUGAR CUBE! Or better yet, you could fit millions of people inside of a GRAIN OF SAND!

Can we build human shaped molecules?

Yes we can! A team from Rice University have made organic molecules for fun which resemble us. They have named the structure “NanoKid” and published their results in the Journal of Organic Chemistry. They even made versions of NanoKid which resemble a scholar and a baker!

Have you ever wondered what gives fireworks their vibrant colors? Well.... it’s your lucky day!

Colored Fireworks — Here you can see a photo of five differently colored fireworks next to the corresponding element that creates the distinct color for each firework. The colors shown are Yellow (Sodium), green (Barium), red (Strontium), blue (Copper), and white(Titanium).

Now for a small challenge

Can you name which elements are liquid at room temperature? I’ll give you a hint, there are ONLY 2!

YOU GUESSED IT! The only pure elemental compounds (which are, compounds made of atoms of only one element) that are liquid at room temperature are Bromine (fuming orange liquid), and mercury (a liquid metal).
