simple‚ it was revolutionary. Scientists became able to study the actual structure and mass of atoms after the discovery of radioactivity. Soon‚ isotopes were discovered‚ as atoms of the same element which have been built up to have different masses. Purpose The purpose of this lab is to investigate the mass properties and relative abundance of isotopes for the “bean bag” element (symbol‚ Bg)‚ and to calculate the atomic mass of this element.

Introduction In “The Radioactive Boy Scout”‚ by Ken Silverstein‚ a small town boy-named David Hahn-dives into the experimental world of not only chemistry but nuclear engineering. In this atomic novel the reader delves deep into the world of a child prodigy and the tale of nuclear romance. This radioactive account of a boy’s journey from small town chemist to a star-crossed engineer is nothing short of explosive. Key Idea 1 In the early chapters of the book David Hahn was found mixing various chemicals

It is said that science is a good servant but a bad master. When we regenerate energy from natural resources like wind‚ sun‚ water and other non biodegradable substances we feel proud but when the consequences lie on ozone layer depletion‚ radioactive radiation make us afraid. I think it’s truly said that good and evil
