1. What does C12H22O11 stands for, and what is it?
2. What do you get if you mix a strip of zinc foil and dilute hydrochloric acid?
3. List the first ten elements of the Periodic Table.
Confusing, and for those who don't know anything about chemistry, doesn't make sense at all, eh? Well, you're lucky to have Marshall (me) as your part time chemistry guide !
Chemistry is a subject about atoms, chemical relationships, chemical reactions and all the other things that might be nonsense to you.
The first thing that you all have to know about chemistry is about the structure of an atom. Atoms are so small that about 10 to the power of 18 carbon atoms in the full stop at the end of the sentence. There a three types of subatomic particle (look in a scientific dictionary):
- Protons (positive charge) - found inside the nucleus.
- Neutrons (neutral) - found inside the nucleus.
- Electrons (negative charge) - arranged in energy levels around the nucleus.
All atoms contain these particles - except the lightest atom, hydrogen, which contains no neutrons.
That is all I'm writing today. Thank you for reading this blog message.
