This essay going to be about an atom. Atom is always around us all the time and ever object are made out of an atom. We, humans, are also made of the atom. Knowing about the structure and what it really is a very important thing to learn as a student. In order to learn about an atom, we will have to understand about Democritus first. So who is Democritus? Democritus is the first human to ever come up with the first atomic theory. Democritus was born in Greece around 460BC. He has a life spend…

Atoms, ions, and isotopes are everything you eat, breathe and see. They are everywhere and everything is made up of them. The first person that aided in the discovery of the atom was Democritus in 400 BC. He is the one that named the atom. The word atom comes from the Greek word atomos which means indivisible. Aristotle which was another flossier in at that same time disagreed with him. He believed that matter could be divide infinitely without changing its properties. At that time more people…

In this Beanium lab, the objective was to make sense of the numbers used to calculate average atomic mass. By separating, counting, and weighing beans we were able to create the numbers used to calculate the weight of one bean. From there, we could use the total number of beans to produce the percent abundance for each type of bean. These were the numbers that we had to produce in order to understand how and why there are many types of isotopes for each element. In doing this lab, we can think…

Uranium is the element that I chose to write about. Uranium is a element that is a naturally radioactive element that comes in a silverish metal when it’s pure. Uranium quickly oxidizes in air and it can be used to color glass that glows greenish - yellow under a blacklight. Uranium is one of the key ingredients in atomic bombs. Only 1.38% of the uranium in the bomb “Little Boy” detonated over Hiroshima underwent fission and there was 140 pounds of Uranium in total. Uranium is an element that…

Natural selection is a concept that has long since interested me, I consider it to mean “survival of the fittest”. Thus, looking upon this title, I deduced that the metaphor, which is used for comparison, implies the following principles of natural selection apply to knowledge development: there is variation in knowledge, the ‘fittest’ knowledge is most suitably adapted to the environment, and superseded knowledge is not fit to survive. Questions and doubts thereby arise: What is meant by the…

was an important step in creating the nuclear model for all atoms. Most importantly, Rutherford’s Nuclear Atomic Model helped Bohr create his Planetary Model, which is close to the model that we use to describe atoms today, and the discovery of the neutron. From his important discoveries, Rutherford was dubbed the name “The Father of Nuclear Physics” and I would like to know why he was first interested in atoms and atomic structure in the first place, and what led him to using the gold foil…

If the explosive goes off along the way, the TCV will "catch all of the primary fragmentation, and [the explosive will] not harm anyone in the immediate area," Haber told Live Science. For instance, after police found the unexploded charge in New York on Saturday, they used a robot to examine and then load the bomb into a TCV, according to The New York Times. Then, they drove the TCV, which was attached to a police vehicle, to a police facility in the Bronx, the Times reported. Most TCVs have…

Collectively the pennies represent a radioactive sample, and each penny is an atom. Because each penny has a 50% chance of decaying it can represent a radioactive atom. When the atoms are grouped together it becomes a sample of a radioactive element. For the simulation to work one has to assume that a coin toss has a 50% chance of landing on heads and a 50% chance of landing on tails. If this is not true then the trial will not be a true half-life because more or less than half of the atoms…

occurring random exponential decay is the process of radioactive decay. Some isotopes of nature are considered radioactive due to a specific characteristic of their nucleus. Radioactive isotopes, or radioisotopes, do not contain the proper amount of neutrons. As a result of this, the nucleus of radioisotopes is unstable. The instability causes them to emit particles or electromagnetic waves from…

Nuclear Energy is energy created from nuclear reactions. There are two known forms of nuclear reactions; fission and fusion. Fusion is the combining of two atoms to form a new one. Fusion occurs when two molecules are moving at extremely high speeds at each other. Then, the two atoms collide and combine together to form a new atom and a massive amount of energy. Unfortunately, here on earth, scientists have not been able to replicate fusion for use. The only known place where fusion occurs is…
