Topic 12 ATOMIC STRUCTURE: Electronic configuration 12. 1. 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). With hydrogen the ionization energy can be

Electronic cigarettes‚ or e-cigarettes‚ have become increasingly popular in recent years. Regular cigarette smoking has been on the decline due to many factors including price‚ health risks‚ and the fact that most public places no longer allow indoor smoking; making it an inconvenience to step outside and light one up. The convenience‚ affordability‚ and health benefits are just a number of reasons the electronic cigarette is rising in popularity. A comparison between e-cigarettes and regular

This act of making such prediction is therefore‚ called forecasting. Forecasts are never finished‚ they are needed continuously and as the time passes‚ their accuracy and their impact on actual performance are meas So it looks like that forecast in itself‚ is not too complicated‚ it becomes complicated once the word ?good? is attached to it. Thus‚ the forecast has to be well thought and planned so it can be called good or adequate forecasting. In order to prepare a forecast‚ one should first identify

Electronics Essay Naturally‚ our day to day lives evolve alongside the progression of technology. Some claim that technology has educational benefits‚ yet others believe that technology creates more problems than it diminishes. Although technology allows children to connect to others with ease‚ its negatives still outweigh its positives in the domain of school. Before adapting completely to this new world of technology‚ schools must consider the negative side of technology‚ including its useless

Appropriate Forecasting Model Forecasting is done by monitoring changes that occur over time and projecting into the future. Forecasting is commonly used in both the for-profit and not-for-profit sectors of the economy. There are two common approaches to forecasting: qualitative and quantitative. Qualitative forecasting methods are especially important when historical data are unavailable. Qualitative forecasting methods are considered to be highly subjective and judgmental. Quantitative forecasting methods

Electronic Gadgets Like Apple iPod - A Boon or Bane It has become a necessity. But like everything in universe‚ electronic gadgets too have two sides to them. I am a house wife. I remember very clearly that evening when my husband came home‚ beaming from ear to ear. He had got a hefty refund on filing his income tax return. And my first reaction was - buy me a washing machine. And I was on cloud nine when my first ever washing machine was delivered. Because I must confess that I hate washing even

In 1965‚ Dr. Gordon Moore working as the Director of R&D for Fairchild Semiconductor published a paper titled “Cramming more components onto integrated circuits”. In his paper‚ he discusses the future of electronics and how these “integrated circuits will lead to such wonders as home computers—or at least terminals connected to a central computer—automatic controls for automobiles‚ and personal portable communications equipment”. He also discusses how the rate in which the number of transistors

ELECTRONIC DICE . TO CONSTRUCT AN ELECTRONIC DICE USING LEDS . BACKGROUND: LED’s History The first known report of a light-emitting solid-state diode was made in 1907 by the British experimenter H. J. Round. However‚ no practical use was made of the discovery for several decades. Independently‚ Oleg Vladimirovich Losev published "Luminous carborundum [[silicon carbide]] detector and

PROJECT IN T.L.E Electronic Components Diodes a diode is a two-terminal electronic component with asymmetric conductance‚ it has low (ideally zero) resistance to current flow in one direction‚ and high (ideally infinite) resistance in the other. A semiconductor diode‚ the most common type today‚ is a crystalline piece of semiconductor material with a p–n junction connected to two electrical terminals. A vacuum tube diode has two electrodes‚ a plate (anode)
