The idea that matter is made up of tiny, indivisible particles or atoms came from these two greek philosophers. The Greek word "atomos" means indivisible.
-
Fire, Water, Earth, Air. Empodocles tried to simplify our complex world into basic elements. He also believed all matter was consious. He also believed matter was held together by a fundamental force of the universe he described as "Love" and pushed apart by another force called "Strife".
-
They beginning to try and change base metals into gold.
-
He described atoms as indivisible and indestructible. Different elements had atoms of differing size and mass. Suggested that chemical reactions were the results of the rearrangement of atoms
-
She theorized, the rays came from the element's atomic structure, these rays are now known as radioactivity. This discovery kickstarted modern-day atomic physics.
-
Thomson realized that the accepted model of an atom did not account for negatively or positively charged particles. Electrons were the raisins and the positive charge was the dough. This explained the electrical properties due to electrons
-
He was able to determine that the energy of each quantum is equal to the frequency of the radiation multiplied by a universal constant that he derived. This constant is now one of the basic constants of physics
-
This model stated that the atom is inherently unstable by radiating continuously, the electron would gradually lose energy and spiral into the nucleus. No electron could thus remain in any particular orbit indefinitely. This means that atoms will eventually lose their chemical properties.
-
Which is the emission of electrons by a metallic surface when irradiated by light or photons. This helped determine the particle-wave duality of electrons.
-
By firing alpha particles at gold foil, and detecting the ricocheting particles, they determined that the atom consisted of a small, dense, positively charged nucleus, with negatively charged electrons surrounding it.
-
He also determined that the number of electrons on the outermost orbit determines the properties of the element. Additionally, his theoretical work contributed to the understanding of nuclear fission.
-
After Rutherford discovered the atomic nucleus and the proton, the discrepancy in atomic masses led to the discovery of a neutral particle through the use of a Neuton Chamber.
-
The notion of matter on the atomic scale might have the properties of a wave were rooted on Einstein's theory that light might be observed as a wave under certain conditions, and as a particle under other conditions. De Broglie’s idea of an electron with the properties of a wave offered an explanation of the restricted motion.
-
Working together with Albert Einstein, he defined one of the two basic classes of subatomic particles. Unfortunately, much of the credit for discovering the boson, or "God particle," was given to British physicist Peter Higgs
-
This principle states that in an atom no two electrons can occupy the same quantum state simultaneously.
-
Schrödinger mathematically determined regions in which elections would most likely be found. These regions are known as Orbitals.
-
He stated that an electron's velocity and position can not be known simultaneously as to measure either with radiation would alter the other
-
News of the splitting of the atom and its awesome possibilities was brought by Bohr to scientists in the United States and ultimately resulted in the Manhattan Project.
-
He also developed predictive computer modeling, using computers to simulate chemical reactions
-
He argues that electron density is more accurate as molecules have no orbits, but electron density remains consistent. Although this goes against conventional theories, there are several pieces of evidence that support this theory.
-
Combining this with quantum computers, humans now live within a simulated reality,
