Ok its chemistry today guyss..

Ok so the basics basics of chemistry.

What is matter?
Well its easy, matter is anything that you can see and feel. Your book would say that matter is anything that has mass and occupies space. But what is mass. Well in easy terms mass is the amount of 'things ' in a body. So matter is anything that is made of things and it takes up space.

Now what is matter made up of?
Think about it only then continue.

Well matter is made up of small things called atoms. What is an atom? Well an atom is an extremely small thing that makes up matter. To give you an idea of how small it is put a full stop on a piece of paper. More than 2000000000 atoms can fit in that small dot.

Ok so what are atoms made up of?

Atoms are like the solar system. An atom consists of even smaller particles called sub atomic particles.
Protons, neutrons and electrons.
Protons have positive charge. (getting complex eh?)
Well a positive charge is the thing that pulls negative things to it.( A proton is optimistic :p)
Neutrons are like this " I don't give a damn about anything" they are completely neutral to anything. They don't attract or repel anything.
The first two things are like the sun. It lies at the heart of the atom called the nucleus.
So what are electrons?
Electrons are negative. They take everything in a negative way. The have a negative charge.
So what happens to them? They revolve around the sun (the nucleus!).
Why do you think they revolve around the nucleus?

That's the end of todays class folks!
