Chapter 1D Warm Up November 28 What is smaller an atom or a cell Name and describe one element that you are familiar with on the periodic table When large blooms of algae die decomposers use all the oxygen in the water to break down the dead algae What is this a result of . 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!. Lab no. 6. In . analytical chemistry. , . Atomic absorption spectroscopy.
