1. Atomic and Molecular Structure a. Students know how to relate the position of an element in the periodic table to its atomic number and atomic mass. The Periodic Table organizes elements by their atomic number - from hydrogen (1) to whatever is the highest one currently known (>105). It is arranged so that similiar members fall in a list such as Chlorine Bromine etc.. The average atomic weight is usually shown with each element‚ but due to isotopes (caused buy nuclear varations)

Historians have placed the decision along racial‚ political‚ and tactical lines‚ while the reasons for the use of atomic weapons are still debated‚ the lasting effects of this event are just as important. Currently there are nine countries that possess the capability to deploy nuclear weapons; countries like North Korea and Iran are currently conducting limited research to development nuclear weapons.

WAS THE ATOMIC BOMBINGS OF HIROSHIMA AND NAGASAKI JUSTIFIED? A bomb which was equal to 13‚000 tonnes of highly-explosive bombs‚ used to make the Japanese surrender‚ but also killing many lives‚ cannot be justified. When the highly-explosive bombs were dropped in Dresden‚ everyone had thought of this as very affective. But imagine how bad the atomic bomb would be‚ which could destroy a city only just by its radiation‚ let alone the actual explosion. President Truman of America made a decision of
