The purpose of this lab was to analyze and examine periodic trends of the first 36 elements that are on the periodic table. Trends that were analyzed and examined are the atomic radius (AR) and the first ionization energy (IE) of the 36 elements. The hypothesis for this lab was that the elements that are in the groups that had the highest atomic radius would be in the same groups as those who have the the highest first ionization energy and the groups who have the lowest atomic radius would be…

Albert Einstein's influence on astronomy. Albert had a big influence on Astronomy. He started to study mathematics, he was lured toward calculus around 1891. Albert originally wanted to be a electrical engineer. But he failed to do pass an examination which would have allowed him to study for a diploma at the Eidgenössische Technische Hochschule in Zurich. He made a plan of graduating as a teacher in mathematics and physics. He got his PHD in 1905. He also created the theory of relativity. A…

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,…

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…

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…

In the chapter “Democritus, Sophie is asked “Why is Lego the most ingenious toy in the world?”(Gaarder 44). This question then leads to the philosopher, Democritus, who is known for the atom theory. Alike the structure of legos, he believed all atoms that made up the universe were “eternal, immutable, and indivisible”(Gaarder 45). Furthermore, Democritus believed all atoms were firm and solid and were all different. Since they were all different, he thought they could join together and form all…

1. Is mercury an appropriate target for AGI? Why or why not? Please clearly cite examples for your reasons. (10 points) There are many reasons that mercury is an appropriate target for AGI. • Both companies are in the same industry of footwear products. • First off the two companies have differentiating strategies and markets that they sell to. AGI will be adding a new market to their company goals and increasing their revenue streams. • AGI strives in the casual footwear segment with a…

Chapter 11, “The Chemical Elements”, was of great interest to me. “Chemistry is the study is the study of the composition and structure of matter (anything that has mass) and the chemical reactions by which substances are changed into other substances (James T. Shipman 285).” In this summary paper, I will discuss some of the highlights of the chapter. The way I see it, God is the original/first chemist. He took His own creations (the elements in our Periodic Table) to make provisions for…

1.Please explain how medical magnetic resonance imaging (MRI) exploits the magnetic properties of the nucleus. MRI exploits the process known as nuclear magnetic resonance (NMR). In fact the technique used to be called simply NMR or NMR imaging, but the “nuclear” was dropped because of the connotation of radiation hazards from unstable nuclear sources, although there is no logical rationale for such fear. In NMR, a sample of material is placed in a strong magnetic field. The nuclei in the sample…

The noble gases are the group of elements which are like no other elements. The noble gases are the elements grouped as the last group, group 18. These elements, from smallest to greatest atomic mass, are Helium, Neon, Argon, Krypton, Xenon, and Radon. Group 18 wasn't always called the noble gases. this group used to be called the inert gassses. They changed the name of thisi group because they are not always inert, or chemically inactive. the first element in this group is the element…
