3. In order to conduct an electrical current, a substance must have charged particles (ions or electrons) that are free-moving, or able to move about throughout the sample.…
But Niels Bohr looked into this and found out that electrons move in paths around the nucleus. Surprisingly these electron can move from one path to another. They can also jump to a path that is a level above. Bohr created a model called the planetary model. This model shows how the electron move in different energy levels.…
Although Joseph John (J.J.) Thomson (1856 - 1940) was mainly a physicist, his discoveries are closely connected to the chemical community. Thomson used Crookes high vacuum cathode ray tube in his discovery of electrons. He found the green beam produced by the cathode ray tube was a completely negatively charged material. Experimenting with different electrically charged plates and magnets in the cathode ray tube and observing the deflection of the rays he had enough evidence to say that particles smaller than atoms existed. By doing this experiment multiple times he compiled enough data to conclude that the mass of one of these particles, which he called an electron, was lighter than an atom of hydrogen by around 2,000 times. He also found the ratio of charge to mass (e/m) would be the same for any electron.…
10. Thomson found that the electrically charged plates affected the direction of a cathode-ray tube beam. True…
Electrons: will be found moving around the nucleus. Will have a negative charge. Do not have any weight meaning they are weightless and have no atomic mass.…
The only reality for an AE is the one they create for themselves…everything is matter – everything is connected as some form of matter or energy and in a cause and effect relationship…
The representation of realism in art or literature of objects, as well as actions or social conditions as they actually are. Realism, quite simply is the act of being real. One displays realism when actions are taken without idealization or presentation in abstract form. There are two types of realism: scientific realism and objective realism. Scientific realists embrace that the characteristic product of successful scientific research is knowledge of largely theory-independent phenomena and that such knowledge is possible (indeed actual) even in those cases…
human eye can view only the color that is reflected, the remaining color in visible spectrum are being absorbed by the plant pigments for energy use.…
In the most general sense, realism is the view that there are entities in this world that exist that are mind-independent. In essence, scientific realism offers a certain portrayal of what a scientific theory is and what constitutes its acceptance based on truth. A scientific realist holds 2 fundamental principles: science aims to give us a literally true account of what the world is like through theories, and that accepting a scientific theory involves the belief that it is true. In stark contrast to this view, constructive empiricism, or rather scientific anti-realism, holds that acceptance of a scientific theory involves only the belief that the theory is empirically adequate, thus differing from the scientific realist view, however it…
In 1913, a Danish physicist named Niels Bohr put Rutherford's findings together with the observed spectra to come up with a new model of the atom in a real leap of intuition. I believe that the Bohr’s model of atom explains well about the atomic theory, because in his experiments it is shown and explained the structure of an atom. His famous suggestion is about that the electrons orbit around the nucleus of an atom. Bohr experimented with atomic spectrum that proved his suggestion.…
1. Because of man’s ignorance and curiosity, arguments for the existence of God have been made over the years. Basically, these arguments are divided into two large groups i.e. logical and metaphysical. Actually, these arguments seek to prove that the existence of a being or having faith with at least one attribute that only God could have is logically necessary.…
Neils Bohr came up with a observation that, since + and – charges electrons on the outside should come crashing into the nucleus cancelling both out. His experiment involved studying light coming from atoms that are ‘excited’ by electricity or flame. The light is made of distinct colour liens…
Anti-realism states that the existence of all objects depends upon human perception: ‘to be is to be perceived’. Idealism states that the immediate objects of perception are mind-dependent, what we today would refer to as sense data but Idealist George Berkeley referred to as ‘ideas.’ The theory suggests that perception is reality meaning that there is no external world to be perceived directly or indirectly.…
In a world where people are ignorant to the things around them. Where there are micro beings living everywhere and inhabiting every crevice there is. These beings are known as atoms. These atoms create matter and the matter creates the world around. Throughout the years, individuals have been researching about the atom and the properties it holds.…
are unthinkingly used to construct social reality. One of these fundamental antinomies is the opposition between objectivism and subjectivism or, in more current parlance, between structuralism and constructivism, which can be roughly characterized as follows. From the…
