Exam Questions and CORRECT Answers
Core Electrons (stay at home Netflix) - CORRECT ANSWER --Electrons in filled shells
-Have limited influence on atomic properties
-Generally unaltered in chemical reactions
Valence Electrons (Free spirit) - CORRECT ANSWER --Electron in shell with largest N
-Determine how an atom interacts with other atoms
-Gained/Lost/Shared
