How Did The Democritus Make The Atomic Theory

John Dalton wrote the modern atomic theory, a fundamental component of that is, the mole ratios of elements in a compound will be small whole numbers.

He is also best known for the theory that was created by himself. The theory of Democritus and Leucippus held that everything is composed of "atoms", which are physically, but not geometrically, indivisible; that between atoms, there lies empty space; that atoms are indestructible; have always been, and always will be, in motion; that there are an infinite number of atoms, and kinds of atoms, which differ in shape, and size. Of the mass of atoms, Democritus said "The more any indivisible exceeds, the heavier it is." But his exact position on weight of atoms is

The atomic theory is very well known across the science community. It took many scientist to get it to what it is today. Aristotle and Democritus are played major parts in forming the atomic theory. They came up with a bunch of theories and made big contributions to the start of the atomic theory.

Bohr is well known for his amazing research on the structure of the atom, he thought that maybe the hydrogen atom was based on the quantum theory that energy can only be transferred in one way, and he also thought that E. rutherford model had some problems, so he fixed

In 5th century BC, a Greek philosopher named Democritus created the earliest form of the theory of matter. He was aware that two halves of a stone were overall identical, so he came to the conclusion that the stone would eventually become too small to cut if it continued to be separated. He referred to these minuscule pieces of matter as "atomos", the Greek word for indivisible. Democritus theorized that an atom differed in size and shape, as well as believing that they were in

First scientist to suggest that all matter is composed of small, indivisible particles called atoms

These contributions now make up the basic grounds for what we know of atoms today. As science grows, we will see that we can go further in this and not only prove these same experiments but improve them. It was the work of these four J.J Thompson, Rutherford, Millikan and, Einstein that we have this information now and are to utilize it to the very last

Anton Lavoisier proved the law of conservation of matter. His experiments on the nature of chemical reactions showed that matter is neither gained nor lost in a chemical reaction. His findings indicated that the mass of the reactants in a chemical reaction is always the same as the mass of the products. Ernest Rutherford used the gold foil experiment and concluded that the atom is made mostly of empty space and has a positively charged center called the

In many ways, Niels Bhor’s model modified the atomic structure that was initially proposed by Rutherford. Rutherford had proposed that electrons circled the nucleus like planets around the sun,

Robert Millikan and Henry Fletcher had to be very clever to pull off this experiment effectively because they couldn’t just take out an electron from an atom and measure its charge. They figured out a way to do this experiment by using tiny drops of oil and balanced them floating in mid air using electricity and gravity. Using thus technique, they were able to

Niels Bohr greatly contributed to the modern atomic model. He provided great knowledge on the atom and physics. He is considered to be one of the greatest physicists of all time because of his contributions to the atomic model. This required the help from a few of his fellow physicists, such as Ernest Rutherford and J.J. Thomson. Niels Bohr created the Bohr model in which he built his ideas from Rutherford and Thomson to create what he thought the atom looked like. Bohr believed that the middle of an atom is a positively charged nucleus with electrons surrounding it. He also discovered that the electrons were not in a specific orbit around the nucleus instead, they jumped around depending on the amount of energy they had.

Bohr was called upon by a fellow colleague named Ernest Rutherford, to help him solve some problems with the Rutherford Planetary Model of the atom. Bohr quickly took the position to help and new that the problem had something to do with the discharge of hydrogen within an atom. After solving this problem and coming up with his own law and model of the atom. This advancement changed physics forever. Bohr’s model was made up of four ideas.

Ernest Rutherford discovered the nucleus and protons inside an atom. He showed that atoms have positively charged particles in their center that mostly consist of empty space. He called the positively charged particles protons, and the center of the atom the nucleus. Rutherford tested Thomson’s hypothesis by devising his “gold foil” experiment, and explained that if Thomson’s atomic model was accurate then the mass of the atom was spread through the atom. For this reason, if he shot high velocity alpha particles, also known as helium nuclei, at an atom there would be very little to deflect the alpha particles. So, Rutherford tested his reasoning by using a very thin film of gold atoms. As Rutherford predicted, nearly all of the alpha particles

As every scientist John Dalton makes mistakes. He made a mistake in assuming that the simplest compound of two elements must be binary, formed from atoms of each element in a 1:1 ratio. This postulate prevented his theory from being accepted for many years. Many of the atomic weights were incorrect and later corrected. For example, he said oxygen atomic weight was seven instead of eight. Although he committed little mistakes, Dalton's theory provided a logical explanation of concepts, and led the way into new fields of experimentation.

John Dalton was an English chemist who came up with his theory of the atom due to his research into gasses. Dalton created his own theory built upon two previous theories that had emerged of the 18th century. Daltons theory focused on five basic theorems that helped him come up with the model of the atom and also into further research. The first theory states that "Elements in their purest state, consist of particles called atoms "his second theory was that "the atoms of a specific element are identical in mass and proportions. His third was that " atoms of different elements can be told apart by their atomic weights" this was a very important theorem as it was going to be the future key of the periodic table. The forth theory was that " compounds are formed by a combination of two or more different kinds of atoms". This was another important theorem as it illustrated that atoms would be changed and added to each other. The last theory was that atoms are indivisible and indestructible. These five theorem 's are now known as Daltons atomic theory which plays an important through new theory 's over time of the atom.
