Jo Adrian P. del Mundo CN 08 3S (A) August 1‚ 2013 Atomic Models The Electron Cloud Model - an atom is comprised of a nucleus made up of neutrons and protons‚ and electrons moving extremely fast around the nucleus‚ forming an electron cloud instead of moving in orbits like what Bohr’s model suggests - proposed by Erwin Schrodinger in 1926‚ when he derived this model using a mathematical equation that he himself made http://1.bp.blogspot.com

History:[1][2][3][4] The story of Silicon Valley started in 1938 with the brilliant Stanford University professor of electrical engineering‚ Frederick Terman. Teaching radio engineering‚ he encouraged his students to work for local companies and to start businesses of their own. It troubled him that his best graduates had to go to the East Coast to find employment‚ especially in the field of radio engineering. His solution was to establish the then-new radio technology locally. Among

Models of the Atom a) Plum Pudding Model The plum pudding model imagines the atom as a positively charged entity that contains randomly dispersed (negative) electrons within it. It is called the plum pudding model because the electrons in the positively charge cloud resemble raisins in a pudding. Thomson realized that all atoms must contain electrons‚ and since the atoms had a neutral charge‚ they must also include protons. This led him and other to think of the atom as a positively charged

Pirates of silicon Valley is a story of the growth of the computer Industry. The movie was based in a historical fact‚ did alter things a little bit of dramatic reasons. The movie begins of IBM during the 1980’s‚ the big brother in the computer world that everyone else feared. One of the two characters in the movie is Steve Jobs along with his friend delight in working computers. They eventually form their own company. Apple Computers are begin making computers. At the Apple Steve Jobs was invited

The electron microscope‚ instrument that produced the first magnified image showing three-dimensional’ and highly magnified image of a small object. It directs a beam of electrons rather than light through a specimen. The beam of electrons is created from an electron gun. This beam then travels through the length of the microscope cylinder‚ which contains the lenses‚ the specimen chamber‚ and the image-recording system. Two types of electron lenses are used‚ electrostatic and electromagnetic

particles called atom. He tried to break down matters into smallest particles. His model was that the matter would stop splitting in halves when it reaches its smallest matter. He called that an atom. * John Dalton In 1803‚ John Dalton proposed a theory. The theory had 4 parts into it. 1. Elements are made of identical atoms. 2. Atoms of different elements are physically different 3. Compounds are formed by a combination of two or more different kinds of atoms. 4. A chemical

MM4012 Module 14: Essay The follow-up product to my silicon semiconductor would be to specialize in microelectronic packaging. My product would be used primarily in high reliability components that undergo complete testing and screening to Aerospace specifications. I would use source control drawings to further refine these standards to specific product processing specifications demanded by unique system designs. Microelectronic packaging is the custom packaging and encapsulation of a desired

The current atomic theory was formed by different scientists over many years‚ each scientist building on or proving theories wrong. Democritus 460-370 B.C. Narrative: Hello! My name is Anna the Atom.

The word atom is derived from the Greek word atom which means indivisible. The Greeks concluded that matter could be broken down into particles too small to be seen. These particles were called atoms. Atoms are composed of three types of particles: protons‚ neutrons‚ and electron. Protons and neutrons are responsible for most of the atomic mass. Example; if a person weighed 150 lbs. approximately 149 lbs. and 15 ounces of that person would be comprised of protons and neutrons while only 1 ounce of

Electron Configuration “Lab” Purpose The purpose of this lab was to explore how electron configurations vary around the periodic table. The lab also helped us examine the relationships between electron configurations and reactions. Analysis The first pattern we discovered was that the sum of the superscripts equaled the number of electrons in the atom. Then‚ we learned that as you travel across the periodic table (starting from hydrogen up to the element of interest) the superscript increases
