    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

    Valence Electrons The valence electrons are the electrons in the last shell or energy level of an atom. They do show a repeating or periodic pattern. The valence electrons increase in number as you go across a period. Then when you start the new period‚ the number drops back down to one and starts increasing again. For example‚ when you go across the table from carbon to nitrogen to oxygen‚ the number of valence electrons increases from 4 to 5 to 6. As we go from fluorine to neon to sodium‚ the

Ionization energy If an electron obtains enough energy it jumps beyond the highest energy level and becomes a free electron: the atom itself becomes a positive ion. This electron transition is represented as follows: n = 1 to n = (. Notation n = ( refers to the “world” outside the atom – beyond the control of the nucleus; any electron outside an atom has no potential energy (energy = 0).

    The Discovery Of The Electron The electron was discovered in 1895 by J.J. Thomson in the form of cathode rays‚ and was the first elementary particle to be identified. The electron is the lightest known particle which possesses an electric charge. Its rest mass is Me <approximately equal> 9.1 x 10 -28 g‚ about 1/1836 of the mass of the proton or neutron. The charge of the electron is -e = -4.8 x 10^-10 esu <elec trostatic unit). The sign of the electron’s charge is negative by convention‚ and

    An electron microscope is a type of microscope that produces an electronically-magnified image of a specimen for detailed observation. The electron microscope (EM) uses a particle beam of electrons to illuminate the specimen and create a magnified image of it. The microscope has a greater resolving power than a light-powered optical microscope‚ because it uses electrons that have wavelengths about 100‚000 times shorter than visible light (photons)‚ and can achieve magnifications of up to 1‚000‚000x

    Electron Microscopy The electron microscope is a very powerful microscope which can see things that normal microscopes cannot. There are 2 types of electron microscope: the transmission electron microscope and the scanning electron microscope. The sample must be in a vacuum so that no air bubbles are on the produced image and also because the electrons are absorbed by the molecules in the air‚ this means that the electron microscope cannot be used to look at living cells.

The nanometre scale conductive island is embedded in an insulating material. Gate signals are capacitive coupled to the island. Two gate signals can be applied to the island out of which one is optional. Here‚ only one electron can tunnel from source to drain. The processes

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
