ibe the propensity of chemical world a timeline is now given in “Your Chemical World” and sense this Timeline does span some eight pages a brief list of the major events that really effected the chemical practice will no be given:-2,400,000Humanoids manufacture metal tools-440 Leucippus decerns that matter is composed of indivisible particles-360 Aristotle rejects atom theories with such power that it I not until the Seventeenth century that it is truly revived400 In Egypt the word chemistry is used to describe the change of matter.1620 Sir Roger Bacon introduces Inductive thinking to pave the way for scientific theory1661 Robert Boyle defines an element1709 Daniel Fahrenheit devises an alcohol thermometer1803 John Dalton puts atomic theory to paper1870 Dmitri Mendeleev creates periodic law and table1911 Ernest Rutherford purposes the nuclear model1945 the first atomic bomb is tested1994The first glimpse of the top quarkThere are many more notable discoveries but in my opinion these are the ones that are remarkable and truly furthered the science of chemistry.Not want this book to come off as completely one-sided “your Chemical World” then takes you on a tour of the deadly results that can happen.
