The Atomic Models!

This post will explain: how does the atomic models have beign modified and changed with the years, all thanks to the scientists that study them.

• Democritus: In 400 B.C. he thought that matter couldn't be infinitely divided.   
• John Dalton: In 1800, he based in his experiments, not only in his own reason and proposed a modern atomic model. It stated that:
• All matter is made of atoms.
• Atoms of an element are identical
• Atoms are able to join and form a compound.
• Atoms can be rearranged by reactions.
• He also stated the law of conservation of matter, which established that "matter couldn't be created nor distroyed, and he also made the law of constant composition.
• Joseph John: he was born in 1856, he was a british physicist that discovered the electrons, isotopes and the invention of the mass spectrometer.
• Thomson Ernest Rutherford: He was burn in 1871, he discovered a noble gas, he stated that atoms are mostly "empty space", and that negative electrons orbit a positive nucleus, he also researched the properties of the radium emanation.
• Niels Bohr: He was born in 1885, he made the Bohr's model, which established how did electrons orbit the shell, how did the electrons could bump to a higher shell, and the two types of spectra.  
• Werner Heisenberg: He was born in 1901, he studied the quantum mechanics. He also stated the principle of uncertainty.

This is just a summary of the important scientist that studied and discovered important aspects of matter and atoms.

My daily use chemical :D

Hi everyone! once again I will post a comment about something that has to do with chemistry :O! (what a surprise uh?! the title of the blog and the first post didn't gave you any clue?!) So well this time, I have to write about a chemical element that is part of a daily product that I use :D ! and well I will not suppose that you already guest :O! so I will tell you wich element did I choose (: and it is the Linalool! what is it?! well it is a chemical compound that is colourless and it's use to have a sweet odour! and yes! it is used as an essencial ingredient for some girl perfumes! for picking the Linalool, I gather around all my perfume boxes!(because I love perfumes, specialy the ones that aren't too sweet :) I prefere the fresh ones ;)! )  and start reading the ingredient part of the box, I realized that besides the alcohol denaturate, my two lovely "Ralphs" and a "BennetonPureSport" also had the Linalool substance in common!
I started researching about it, and I found out that, it occurs naturally in many essecial oils! (specially the cytrus ones!)
I also learned that some people tend to have allergic responses to the Linalool :O! so I really feel very lucky! because must of times i'm very allergic to lots of things, for example : eating egg, or the weather changes!
Afortunally i'm not allergic! so I can put all the perfume that I want! :D
Well that was all that I had for this post! I will continue writting and I hope you liked this "article" ! :D
Take care!
bye! :D

Chemistry all around me! :D

Hello! Welcome to my new blog! created for talking about chemistry, every doubt or concern that I have about it, things that I found really interesting and amezing, and more stuff!! :D! Well the first thing that I would try to explain is the realistic name for my blog (: Is not mean.. is just the truth! is proved that magic doesn't exist! if it is not a trick or ilussion is a chemical reaccion that happens everywhere around us! for example raining: well is not magic, is simply a change in the physical properties of water :O! LOVE is not magic! it's just a set of chemical reactions going through or brain making us feel things we have never experienced before and that we find pleasant... But eventhough magic doesn't exist! that's no reason to get disappointed or sad... because maybe if we think and analyse, chemistry (that is the one that really exists!) is better than magic! because it makes all the things that we think "magic" can do and more! and the best thing is that, if we study, we can know why did they happen, how, and which are their reactions! we can create our own "magic" whenever we want! isn't that awsome!?
Well this was my first post! I hope you enjoy it and found it interesting! post anything you want! I will read it and answer it as soon as possible!
bye!! :D
