The Historical Development of the Atom and it Implications.
There were four scientists who came up with different theories about the atom and its structures. These four were John Dalton, Joseph John Thomson, Earnest Rutherford, and Neil Bohr. They each had different theories and ideas about the atom.
John Dalton.
Dalton believed that atoms were the smallest parts of matter. He believed that all atoms were the same but ranged in weights. He also believed that when elements mixed there atoms mixed to form a compound with different atoms in it.
Joseph John Thomson.
Thomson believed that atoms had particles in them called electrons. He found out that the electron was negatively charged. He discovered that at very low pressures some gases conduct electricity. He found out that electrons weigh about 1/1840 of a hydrogen atom. He also believed that the atom had the electron scattered through it.
Earnest Rutherford.
Rutherford was the first man to split the atom. He concluded that the atom was mostly empty space. He came up with a new model of the with a centre core and electrons orbiting that core.
Neil Bohr.
Bohr improved on Rutherford's theory of the atom. He came up with another theory that suggested that the electrons orbiting around the outside of the core were organised into shells, and they could jump from shell to shell if the gained or lost energy.
There are many different applications of nuclear science that have been used to enhance the human way of life. Some of these include nuclear power stations, nuclear weapons, radiation therapy, and smoke detectors.
Nuclear power stations have definitely help people to achieve their goals. Power station provides an easy way of getting power to people all over the world. Though nuclear power station do run the risk of a nuclear spill which would wreak havoc on surrounding towns and city for 100's of years afterwards, like the incident in Chernobyl, there have not been very many accidents relating to them.
