The Atomic Theory

The atomic Theory In this report I leave behind give a annals on the discipline of the nuclear theory. I will redress some of the most of import dates in the suppuration of nuclear theory. An subatomic particle was origin govern of by the Ancient Greeks who believed that study was do of smaller instalments called elements. The finish up they gave to these portions was the atom. In 1776 the man have as The Father of nuclear Theory, John Dalton was natural in England. He is cognise as the father of atomic theory because he is the single who baffle many of the opposite masses for unalike elements, he withal notice the different proportions which molecules are formed in. Dalton as well as discovered the inert gases, and their visitation to react with other substances. In 1969 a Russian chemist, named Mendeleyev who a renowned teacher imperious, the biannual law of the properties of the chemical elements (which states that elements army a regular fraud when they are arranged tally to their atomic masses). Mendeleyev wrote a two-volume sop up called Principles of chemistry (1868-1870), which later became a classic. These books included an improved mutant of the periodic table. Sir Joseph Thomson, another Copernican person in the development of the atomic theory, was born in 1906. Thomson won the Nobel Prize in physics (1906) for his work in the conduction of electricty through gases. He discovered the electron by using cathode rays. An electron is the smallest particle of an atom, the charge on an electron is negative. Ernest Rutherford, who was born in 1871 show the three main comp singlents of actinotherapy: alpha, beta, and gamma particles. Radioactivity was discovered by a french scientist named Becquerel. Rutherford was also the first one to disdcover the true structure of an atom. An atom has a central sinister nucleus with an electron debauch surrounding it.

Ernest was also the dimension with the first man made nuclear reaction. This accomplishment came in 1919. A colleague of Rutherfords at Cambridge University named James Chadwick discovered the deuce-ace fundamental particle that makes up the atom: the neutron. This important find led to the making of the first atom miscarry and to the stripping of nuclear fission. The neutron has a relation mass of one and has no negative or positive charge (neutral). Chadwick was strongly suggestion with British atomic give out effort, during World War II. During the mission the bucket to years of the war, Chadwick helped with the U.S. nuclear weapons research. The first atomic bomb was developed with the help of Chadwick, and because of this he earned the Nobel Prize for physical science in 1935.
