Electron Configuration Ch.4 Worksheets Answers document sample
Document Sample
2009-2010 Chemistry, Chapters 4 & 5: Atomic Theory
Essential Questions: What are we made of?
• How are scientific models developed?
• Do atoms exist or are they just concepts invented by scientists? What evidence is there in your everyday life for
the existence of atoms?
• How did the understanding of the atom affect historical events?
• How have historical events affected the model of the atom?
• What do we think the atom “looks like” now?
• If the atom is mostly empty space, why doesn’t my butt fall through the chair?
• How are light and electrons related?
• How do we “see” where electrons are located in the atom?
• Why is the location of electrons so important?
