3. Atom Basics What does Borh’s model look like?
Center with number of protons and neutrons labels
Rings with dots on them to represent electrons
1st ring has 2 dots, 2nd ring has 8 dots, 3rd ring has 18 dots
What does a Lewis Dot model look like?
Elements symbol with dots around it to represent the number of VALANCE electrons
Remember put one dot on each side to begin with, only double up with 5 or more electrons.
