Atomic Structure: Transcript
Chemistry Learning Goals To be able to explain and draw atomic structure Elements Elements are the building blocks of all matter on Earth Elements are made up of atoms Differences in . 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.

When . are zeros significant? . . When . do you use the fewest number of Significant Figures?. Objectives. The Structure of the Atom. Properties of Subatomic Particles. Textbook Pages 4-5. Lesson Objectives. Appreciate that there are various models to illustrate atomic structure. Know that early models of atomic structure predicted that atoms and ions with noble gas electron arrangements should be stable. Advanced Chemistry. Ms. . Grobsky. Food For Thought. Rutherford’s model became known as the “planetary model”. The “sun” was the positively-charged dense nucleus and the negatively-charged electrons were the “planets”.
