Multiplication table

found in different oxidation states, that is, different ionic states e.g. Iron (Fe) has two oxidation states, Fe (I) and Fe (II). This means that Iron can have the ionic form of Fe+2 or Fe+3. There is a density trend on the Periodic Table, but…

What is a Periodic Table and what is it used for in science and our everyday lives? On entering the chemistry laboratory at Mercer University, for Science 100 a large colorful chart displaying rows and columns of cells, was hanging over the chalkboard. I immediately felt a bit intimidated and my heart began racing. I questioned myself as to what am I about to experience? Moving closer to examine the chart, I felt as if the bright colors on the chart were generating warmth (energy) and…

term used to describe the trends of the periodic table pertaining to the element’s properties. One of these trends is known as atomic radius. Atomic radius is the term referring to one half the distance between the nuclei in a diatomic molecule. This atom’s size depends on the size of the electron cloud surrounding the inner nucleus. As one moves across a period, the atomic radius is smaller. In other words, when one moves across the periodic table from left to right, the atomic radius gets…

He is known for his work on the Periodic Law and the creation of the very first periodic table. Mendeleev dedicated many years of his life to collecting information about all the 63 elements that had been discovered during his time. Mendeleev had noticed that there were groups of different elements with very similar atomic masses and other chemical…

by products. In order to meet this requirement, I designed the dimensional model by using the periodic snapshot approach so the company could see the quantity-on-hand of each product at the end of the day. This design has two dimension tables and one fact table: DimDate, DimProducts, and InventoryFact. There is no need to have the DimStores in the schema because the company has only one store at this moment. Second, the company also would like to analyze the audit trail of shipments of…

The gradual transformation in data quantity has resulted in emergence of the Big data and immense datasets that need to be stored. Traditional relational databases are facing many difficulties meeting the requirements of the volume and heterogeneity structure of big data. NoSQL databases are designed with a novel data management system that can handle and process huge volumes of data. NOSQL systems provide horizontal scalability by supporting horizontal data partitioning across heterogeneous…

Theq element on the Periodic table that is best representation of my personality would be element 13, Aluminum. Properties of Aluminum its included high melting point, conductivity, malleability, and non-toxicity. Aluminum’s high melting point represents my determined personality. This is because I can face adversity well. Even when situations occur that are extremely unfavorable I am able to keep a cool head and think straight. I can persevere and stay strong allowing myself to solve and get…

Gilbert Lewis first introduced his theoretical dot structures in 1916. Today, these same dot structures are used to illustrate the chemical bonding nature of atoms. How did Lewis formulate these brilliantly simple representations of nature? The Lewis Dot Structures we know today actually derive their functionality from Lewis’ own model of the atom, the Theory of the Cubical Atom. This essay will explore the functionality of Lewis’ cubical atom and how this model led to the Lewis Dot Structures.…

Twelve Tables, an 5th century B.C. Roman document providing law related to various aspects of Roman life, quite a bit can be gleaned about some of the major aspects of Roman society at that time. From the importance of fatherhood to evidence of an ongoing class-war, these laws provide a wealth of insight into various societal qualities of Rome at the creation of its first true legislation. Before any quality interpretation of the text, it should be noted the context within which the Twelve…

His use of the term “pivots” (2) suggests that her movements are efficient and mechanical rather than natural, and that she spends no more time than is necessary at his table. As he repeats three times that she smiles at him, he conveys the sense that her smiles are automatic and part of her waitress persona rather than indicative of any genuine pleasure in his presence. He also mentions that she brings him a menu, brings…
