It is obvious that during ancient times, there was much debate revolving around the existence of atoms and their affect in life. Though after is was decided that atoms were made up of many particles that could not be broken down anymore. By the 19th century, scientists had finally started to and figured out that it was possible to combine elements into new substances. This was then named a compound. As the book goes more into the definition of definite proportions, and how there are nine parts of water, my mind started to wander off. All of this seemed pretty confusing. It was very interesting though to learn that no matter what, atoms are indestructible and can only be rearranged. As studies became more advanced, scientists were able to determine a scale of the relative mass of certain atoms. Hydrogen is the lightest element in the knowledgable universe clocking in at 1.01 grams per mol. All of this is pretty cool to finally be able to understand. Adios
There are many ways to interpret the meaning of an element. They are commonly described as bodies that are not able to be divided into other bodies, only divisible by themselves. In order to organize the elements, different strategies were used but chemists world wide knew that they had to be divided up into families consisting of physical and chemical properties. Elements share two types of properties; physical and chemical. Physical properties are measured when the substance’s chemical identity does not change. Chemical properties are displayed when a substance undergoes a chemical change and a new substance is formed. Whenever elements combine with oxygen molecules, they always for oxides. Pretty interesting stuff.
