Chemistry Unit 1 Day 2 continued

Learning: Students will learn about the effects of electrons on atoms by doing a simulation using words (ions, atomic mass, neutrons, protons), notes, and check up partners.

Questions:

1. If an atom has 8 protons, how many electrons does it have? (book or brain)
2. Why are valence electrons important? (book or brain)
3. Why do we say electrons are in a cloud? (book or brain)
