A mixture of elements is what is known as compounds. Chemical reactions occur when particles react with each other and atoms in molecules get rearranged. Reactions happen either rapidly or slowly. The speed of a reaction is known as the rate of the reaction. This speed of chemical reaction depends on many factors such as temperature, particle size of reactants, and the intensity of reactants.
Scientist continued to develop the world's knowledge of the atom. In 1896, Henri Becquerel accidentally discovered radioactivity(Doc.1). Furthermore, in 1911, Ernest Rutherford discovered atoms were made of smaller particles and that they had a positively charged nucleus(Doc.1). Throughout decades, scientist have honed ,developed, and continued in the study of the science of the
AP Chemistry enthralled me with its indecipherable French theories and alphabet of Greek formulae, for my studies transmuted these into poignant prose. Information that had once seemed impossibly complex soon flowed from my mind as effortlessly as a pleasant conversation with a friend, and I began tirelessly consuming the material as though I had been starving for it. Cravings which had been subconsciously growing in me since childhood were relieved with a feast of answers: The fundamental concepts of existence revealed in a humble high school classroom. Soon, the only thing more insatiable than my curiosity was my ambition to apply this newly-acquired knowledge to the aching problems of the world. Studying the very building blocks of the universe
Through this experiment, Rutherford disproved J.J. Thompson's Plum Pudding Model, and allowed people could better understand the structure and function of the atom. Also, it motivated other scientists to study the atom more fluently. The results of Rutherford's experiments are still considered valid, but we now know that the nucleus is also composed of neutrons, thanks to experiments James Chadwick, and not just protons and electrons. Niels Bohr came up with the idea of electron shells, which explains how and why chemicals react, and where electrons are located in atom. The conclusions of the Gold Foil Experiment represent one of the most pivotal scientific discoveries in human history.
This statement gave the conclusion that energy can be produced from matter. If humans could use this formula to create pure energy from a penny, it would be able to power New York City for two months. He also is responsible for the science behind the atomic bomb (Schwartz). Albert Einstein gave us a larger view of the world around us, so we can go where nobody has gone
One of his most well known is his Bohr model, which shows an atom 's structure, is used in all classrooms that teach chemistry. He also suggested that an electron would drop from a higher orbit to a lower one, which would release a photon(electron configuration). This would later become a foundation upon which quantum theory stood on. Niels Bohr has always been accepted into the
Response: I, Democritus, state that there is motion in the world, due to the fact this is how one can account for the perception of different qualities. There are two realities we must account for: atoms and the void. The properties of the atoms are they are basic, indivisible units that do not come to be or pass away, do not change and are unified. Atoms are infinite in number, come in different shapes and postures, have existed for ever and are all uniform. The atoms are too small to be detected by the senses, but they make up everything in the world.
Democritus was born in Abdera, geographical area around 460 before Christ. His precise influences area unit tough to cut loose those of his teacher Leucippus, as they're usually mentioned along in texts. Their theory on atoms, taken from Leucippus, bears a passing and partial similarity to the nineteenth-century understanding of atomic structure that has crystal rectifier some to treat Democritus as additional of an individual than different Greek philosophers; but, their concepts fresh on terribly completely different bases. Mostly neglected in ancient Athens, Democritus was nevertheless documented to his fellow northern-born thinker Aristotle. Philosopher is alleged to possess scorned him most that he needed all his books burned.
PARACELSUS STARTS A MOVEMENT Aureolus Philippus Theophrastus Bombastus von Hohenheim, (1493-1541), known as Paracelsus (the second Celsius!) gave the word bombastic to the lexicon of all modern languages! He was the son of an alchemist and learned all there was to know about alchemy from his father. He then went to Basle University in Switzerland to study, but became dissatisfied with their complete reliance on authority. He then set up to wonder throughout Europe, acquiring knowledge of nature first hand.
In 1913, he introduced “the trilogy”, three quantum papers describing the Bohr model of the atom which is currently used in many chemistry and physics texts. This brought him widespread recognition. His model presents atoms as small positively charged nuclei circularly orbited by negatively charged electrons. The electrons have separate orbits with the last orbit’s number of electrons significantly affecting the element’s chemical properties. He suggested that electrons are confined to particular orbits and can jump to other orbits by absorbing or emitting energy.
This theory also shows how the matter changes its states. The processes on how matter changes its states are the following: melting, freezing, boiling, condensing, evaporation, and sublimation. Ludwig Boltzmann and James Clerk Maxwell developed kinetic particle theory. This theory supports the study because it deals with a matter, which is the soup where it is in a liquid state.
Modern educational institutions and organizations are highly creative of hypermodernity, the evolvement of technical rationality and militarization of knowledge (Atkinson, 2004; Benn & Chitty, 1996). These arguments fit well with the tenets of chaos theory. Chaos theory reminds us that complex systems have the ability to create order out of chaos. This is the case at a balancing point, called the ‘edge of chaos’. At the edge of chaos, the system is in a kind of suspended vacillation between stability and total dissolution into chaos (Cohen & Stewart, 1995).
Complexity Theory Complex theory is another kind that is closely related to chaos theory. A complex systems is one in which numerous independent elements continuously interact and spontaneously organize and reorganize themselves into more elaborate structures. Thus, complexity has the following characteristics: • A complex system has a large number of similar but independent elements or agents •
This individual person who ignited the argument on theoretical physicists and changed it forever? Erwin Schrödinger known as the father of quantum physics, Schrödinger is an Austrian physicist who ignited the debate on quantum physics. In the early 19th century, Schrödinger created a new theory of quantum physics which began the debate. In the late 19th century he created his wave mechanics to prove his theory was correct.
