PART 2
Discussion questions
Each answer must be in your own words
100 words per answer
1 What is The Quantum mechanic mode?
2 Why do you think we spend so much time discussing electrons and valence electrons in particular? Why are they so important in understanding chemical reactions?
3 What is the Bohr model ?
4 Why is it important to understand how electrons fill in the space around the nucleus? How does that help us understand the behavior or atoms?
5 what is electromagnetic spectrum ?
6 what are The bonding theories?
7 what is the lewis model?
