Quantim Theory
Quantim Mechanics is abranch of mathematical physics that deals with the emission and absorption of energy by matter and with the motion of material particles. Because it holds that energy and matter exist in tiny, discrete amounts, quantum mechanics is particularly applicable to Elamentry Pprticlesand the interactions between them. According to the older theories of classical physics, energy is treated solely as a continuous phenomenon and matter is assumed to occupy a very specific region of space and to move in a continuous manner. According to the quantum theory, energy is emitted and absorbed in a small packet, called a quantum (pl. quanta), which in some situations behaves as particles of matter do; particles exhibit certain wavelike properties when in motion and are no longer viewed as localized in a given region but as spread out to some degree. The quantum theory thus proposes a dual nature for both waves and particles, with one aspect predominating in some situations and the other predominating in other situations. Quantum mechanics is needed to explain many properties of matter, such as the temperature dependence of the specific heat of solids, as well as when very small quantities of matter or energy are involved, as
Another scientist that created a model of the atomic structure of an atom was Rutherford. His model was an model in which the the atom was held together by an electrical attraction between the nucleus and the electrons. by electrical attraction between the nucleus and the electrons. In this model the electrons travelled in relatively distant orbits around the nucleus. The model eventually proved successful in of chemistry and everyday physics. Subsequent studies of the atom divided into investigations of the electronic parts of the atom, which came to be known as atomic physics, and investigations of the nucleus itself, which came to be known as nuclear physics. Another scientist that made a break through in the current model of the atomic structure of an atom was known as Thompson. In 1895, Thomson discovered the electron. His evidence came from the experiment he did using an apparatus that allowed him to see the glow of the stream of negatively charged particals released when a gas is subjected to intense electrical forces. These particals are known now to be electrons. It was his experiments that proved that the atom was not an indivisible particle. Instead, it was made up of different particles itself. In 1906, Thomson recieved a nobel prize for his discovories. Thomson's model of an atom was a solid sphere with electrons embedded in the positive part of the atom. The positive part of the atom makes up the bulk of the atom's mass and volume. It was hypothesized that the positive part of the atom w
