Explaining the Atomic Theory

Water, earth, fire, air, long ago were once known as the four main elements. Ancient Greek philosopher Aristotle contributed to the theory by adding a fifth element, aether. Before Aristotle though, the Greek believed everything was made up of the four elements. Hippocrates used the four elements to describe the four humor theory he proposed himself. Despite all the belief in the theory of the four elements, soon it was discovered that the four elements theory was wrong. Near the end of the 17th century, Robert Boyle disproved the theory with a book he published, called “The skeptical chemist”.

The atomic theory came into play around the early 1800’s.

Proposed by John Dalton, the theory states that there is a special atom for every kind of element. He modified the components of the elements, and stated that they are made of smaller molecules called atoms. Neil Bohr developed a modern model of the atom in 1913, the one that we know today.

It’s represented by outer rings, and the atoms inside the rings. Throughout history, many people have contributed to the atomic history, to produce the periodic table we know today. The information provided here may be used on the AP exam, in the case that the prompt specifies why chemistry is an important aspect in life, as well as how science has changed over time. This can also be used to show that even the correct people can be disproven, in the case that the prompt asks how people change based on actions.
