floors. Your last step is to examine the nails‚ screws and other elements of the building. Which method do you think is closest to your study of chemistry thus far? What are the pros and cons to proceeding one way rather than another? Write 3–5 paragraphs and submit the short essay to your teacher. Have fun! Method one is most similar to Chemistry. This is because the table of elements is like the building and we began by looking at it as a whole and then learned the individual parts of it. First

Using chemistry for electronics and vice versa The microelectronics industry is continually striving to miniaturize conventional silicon-based electronic devices to provide higher performance technology that can be housed in smaller packaging. Progress resulting from this miniaturization is evident from the rapid advances in consumer electronics‚ such as cell phones and laptop computers‚ that have been observed in recent years. Now‚ silicon-based molecular electronics -- a complementary technology
