Electron configuration

determined by the electrons in a compound.1 As electrons move around, they can absorb energy and become excited. The energy, and thus the wavelength of light, the electrons absorb is determined by the type of atoms found in the compound and how those atoms are bound together. Different environments for electrons will also determine how much of a particular wavelength of light can be absorbed, a parameter which is reflected…

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, accumulating scattered angle of some incident electron is more than 90 degrees, they will re-emit from the surface of the sample. The characteristic of backscattered is high energy and close to the energy of incident electron, the resolution is low. On the contrary, the energy of secondary electrons is very small and less…

His major discoveries came by doing experiments with cathode ray tubes which have electrons that emitted light when negative voltage and metal plates were added, this was the discovery of the electron or corpuscle as he named it (Unknown author, 1997). A cathode tube works by creating gaseous discharge, which "occurs in a gas at low pressure when subjected to an electrical potential difference…

Source 1:http://van.physics.illinois.edu/qa/listing.php?id=13451 Some kinds of metals (like steel that the needles are made of) are made up of billions and billions of individual atoms that each have the properties of a microscopic magnet. The atoms in steel naturally tend to get together in tiny little groups called domains, and within each domain the atoms tend to point in the same direction, which makes the domains behave like a tiny little bar magnets just like the kind you have…

The problem with synthesizing this molecule is that it contains unpaired electrons in two of its outer carbons. These free electrons cause the molecule to oxidize almost instantly as these electrons react to try to find stability. The researcher team form IBM has found a way to overcome this obstacle. By starting with the molecule dihydrotriangulene, triangulene with a hydrogen attached to each of the unpaired electrons. The researchers were able…

Throughout this exhibition, I have created one specific theme—to take you through the technique of gilding and the material of gilt bronze. Gilding or Ormolu is a “decorative technique for applying fine gold leaf or powder to a solid surface such as wood, stone, or metal to give a thin coating of gold.” In this case, the exhibition will revolve around gilt bronze Asian artwork. Let us take a tour through multiple pieces and learn about the gilding technique, and how the material has held up…

Jessica Vandeventer 16 March 16 Static Electricity or Electrostatics Purpose/Question- The purpose of this experiment it to explore static electricity and to explore how charges effect one another. Hypothesis– Any like charges will repel each other and any unalike charges will be attracted to each other. Data Tables/ Graphs – Charging Material Pepper Salt Paper Aluminum Styrofoam Uncharged Nothing Nothing Nothing Nothing Nothing Cotton Nothing Nothing Stuck to ruler Stuck to ruler Nothing Fur…

and purify it, proving Mendeleev’s predictions. The element would be named Germanium after Germany. Structure. Germanium is found naturally in five different forms of isotopes. The most stable isotope, 72Germanium, is composed of 32 Protons, 32 Electrons, and 40 Neutrons. However, the most common isotope is…

CDM Cases is a retailer store that sells cases of all different variety such as colors and shapes. Our products are made up of the best material that could be found on the face of this earth. Our store is located in Dinuba, across from Walmart. Our store is unique because we provide the customer with the best service, and the best products as well. Also we keep everything organized based on its type for example the IPhone cases are in there own section so that the customer would not have hard…

The Large Hadron Collider (LHC) is a particle accelerator made of superconducting magnets, built on September 10th, 2008. It can be found between the border of France and Switzerland, near Geneva, 100 meters underground. The Large Hadron Collider is a machine that was built with the ability to accelerate subatomic particles to very high speeds, which requires chilling the magnets to ‑271.3°C. This is done through the use of electric or electromagnetic fields, two hadrons are sent through the…
