chemistry into this chapter. He brings up the Bohr model, he states atoms being similar to the solar system. The way electrons go around the nucleus is the same way planets orbit. Elements have the ability to be present even with a varying number of neutrons. This is to be called isotopes. His point with this is that these isotopes are very balanced while others may be not so balanced. This will then be called radioactivity. Every isotope that becomes radioactive eventually decays. So to…

SEM is a kind of microscope to observe the topography of materials. SEM has some advantages: it has a large depth of field and we can observe the 3D image of the sample and analyzing its topography, its magnification range is widely and we could make sample easily because of the X-ray spectrometry, which can determine the elements of sample. When electron beam attack the sample, incident electron will be diffracted and change the direction or even loose some energy. During this process,…

their relative masses and charges (Bbc.co.uk 2015). Particle Relative Charge Relative Mass Proton +1 1 Neutron 0 1 Electron -1 2. Explain the meaning of the terms, ATOMIC NUMBER and MASS NUMBER of an atom in terms of sub atomic particles. The atomic number refers to the number of protons in an atom, the mass number refers to the number of protons plus the number of neutrons (Bbc.co.uk 2015). 3. A neutral atom contains the same number of protons and electrons. Briefly explain…

that could possibly cause cancer. At which human health is more important than energy.Another problem fission suffers is the fact that disposing the waste is a challenge and if not done properly it can be hazardous to the people. The high energy neutrons that are produced by the fission reactions can make non radioactive substances that would be in the reactor and make them…

Nuclear power, we have all heard of it. Or most of us have, nuclear power is created by nuclear fission (“Nuclear Power for the 21sr Century”). The process of uranium isotopes in a controlled environment being split. As you know any action takes energy and when energy is being used or changed a by-product is made. In most cases it is thermal energy, which is heat energy. That is exactly what is happening in a nuclear power plant. When one uranium isotope is split a chain reaction is created in…

The Atomic Theory The Atomic theory is just another law or principle of science, its the very foundation of all that science includes! The laws and principles of science were able to be tested because of this theory! We are going over everything about the atomic theory including its beginning, the history of the atomic theory, and why it is so important in the first place. We will also go over the many models produced by scientists over the years and why they were right or wrong and then…

having too many or too few electrons, neutrons or protons and you have a radioactive element.The element becomes unstable as each part holds another part on so having too few means that the link may be too weak to hold it together then having too many means there pushing others off the particles as there are too many attached to the main atom for them to share.Beta particles are formed when the neutron decays and forms an antineutrino particle which contains neutron and a few protons this then…

charged electrons. Here, the electrons represents the plume in the pudding of positive charge. Hence his model was known as plum pudding model. It was also known as watermelon model where the positive charge was the flesh of the watermelon and the electrons were the sects. a) J.J. Thomson who discovered the electron in 1897, proposed the plum pudding model of the atom in 1904 before the discovery of the atomic nucleus in order to include the electron in the atomic model. b) In Thomson’s model,…

In this new era of 21th century, our world is surrounded by energy even our eating foods also having energy which is chemical energy. In physics, energy is defined as a property of objects which can be transferred to other objects or be converted into many different forms (encyclopedia 2016). Energy can be differentiated into two groups which is renewable energy and non-renewable energy. Renewable energy group is defined as the group of energy which can be replenished naturally in a short period…

The Greeks certainly thought so, they were great believers in fatalism and thought everything that happened was predetermined. They predicted their future in various ways whether it was through coffee grounds, palm readings, or through the stars. Most commonly, they found the “truth” through the oracle. According to the Greeks, Apollo the god of the oracle spoke through the priestess Pythia who informed and gave advice to the many citizens who seeked it. They also believed that “fortunes of…
