MODULE1 TOPICpBLOCK ELEMENTS CHAPTER 15 GROUP ELEMENTS INTRODUCTION There are 6 elements in 15 group of periodic table ie Nitrogen phosphorus arsenic antimonybismuth amp moscovium. At the start of WWII in 1939 the atomic bomb had not yet been invented. However, scientists discovered about that time that a powerful explosion might be possible by splitting an atom. This type of bomb could destroy large cities in a single blast and would change warfare forever!. Bell Ringer . Review..Frame. your argument. Bell Ringer: What was the name of the program to build the Atomic Bomb? Who was the lead scientist?. Agenda: Notes/discussion. Objective: Through Discussion and notes students will begin to understands the steps leading to the dropping of the atomic bomb.. Lab no. 6. In . analytical chemistry. , .

The immense destructive power of atomic weapons derives from a sudden release of energy produced by splitting the nuclei of the fissile elements making up the bombs' core.
