Atom and Periodic Table Review
Chapter 4 and 5
Atom Basics• How do we determine the number of
1. Protons2. Neutrons3. Electrons4. Valance Electrons5. Energy Levels
1. Look at atomic #2. Mass – Atomic #3. Look at atomic #4. Look at group #5. Look at period #
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.
Periodic Table Basics• Where are the following types of elements located– Metals– Nonmetals– Metalloids
– To the left of the solid stair step line– To the right of the solid stair step line– Sitting on or below the stair step line
