The reason that I am interested in doing my research essay on the Atom Bomb is because I have always been interested in politics. How our world works‚ and what has effected it’s course‚ in my opinion‚ is one of the most important subjects to learn among our peers. After careful thought‚ I chose the atomic bomb because it is one of the few past inventions that still threaten us today. My base intention is to try an understand why men desired such an easy‚ yet consequential‚ means of war. What drives

Hi‚ my name is water molecule! H2O for short. I live in the bottom of a well. I come from 2 hydrogen atoms‚ but I have an oxygen atom in me! Down here in my well‚ we have a swell time together. In our liquid state‚ we are not too far apart‚ nor too packed together. It’s really great being a liquid! I feel bad for my cousin CO2. He is probably sublimating into a gas from a solid‚ or as a gas‚ freezing back into a solid. He has no melting point‚ only a freezing and boiling point. I’m SO glad I will

Periodic Table Trends Quiz 1. The most reactive metals are located in the lower left hand corner of the periodic table 2. Which of the following atoms listed below has the largest atomic radius? Ca 3. Compared to the atomic radius of a rubidium atom‚ the atomic radius of a strontium atom is smaller. The smaller radius is primarily the result of the strontium atom having greater effective nuclear charge 4. An element is most likely to have properties similar to those of another

The development of Periodic Table Elements such as gold and silver have been known since the earliest times. In 1649‚ a German alchemist‚ Hennig Brand made the first scientific discovery of an element‚ phosphorous. In the next 200 years‚ knowledge about the properties of elements and their compounds was gained. By 1869‚ 63 elements had been discovered in total. Scientists began to categorise those elements according to the similarities of their physical and chemical properties‚ which become the

Jenkins Changing of the periodic table Today‚ the periodic table organizes the elements in horizontal rows‚ or periods‚ by order of increasing atomic number. The elements are also organized in vertical columns‚ or groups‚ based on similar physical characteristics and chemical behavior. I believe the periodic table will continue to evolve as new elements are discovered. One of the earliest attempts to organize the elements based on their chemical and physical properties was made by German chemist

Revolving with Electrons Have you ever wondered exactly how the elements on the periodic table are organized‚ what the groups on the periodic table mean‚ and how electrons work in an atom‚ compound‚ and chemical bond? The way elements are organized on a periodic table has to do with the characteristics that they hold. There are groups‚ periods‚ compound formation and color coordination in a periodic table. The periodic table is organized in many ways. As stated by Chem4kids.com‚ "Each element is
