MONDAY SEPT. 22ND

• PLEASE GRAB A BOOK
• HAVE FIRST 15 MIN TO FINISH UP BOOK WORK IF
  NEEDED
• TODAY TAKING NOTES ON CHEM
• REMEMBER QUIZ TOMORROW!

2

• WHY?

3
ATOMS

• ALL MATTER ON EARTH IS COMPOSED OF ATOMS, LIVING
  AND NON-LIVING!
• WHAT DOES AN ATOM LOOK LIKE? CAN WE SEE IT?
  (atomic theory)

4
ATOM STRUCTURE

• SUBATOMIC PARTICLES
• PROTONS POSTIVE CHARGE
• ELECTRONS NEGATIVE CHARGE
• NEUTRONS NO CHARGE
• HOW DO THEY INTERACT?

5
ATOMIC STRUCTURE

• ATOMS NORMALLY HAVE THE SAME NUMBER OF PROTONS
  AND ELECTRONS (NUMBER OF NEUTRONS VARIES)

WHAT HAPPENS IF YOU HAVE MORE OR LESS OF ONE
SUBATOMIC PARTICLE?
6
IONS
DIFFERENT AMOUNTS OF SUBATOMIC PARTICLES

• IONS ANY CHARGED ATOM
• HAVE GAINED OR LOST A PROTON OR ELECTRON
• MORE PROTONS CATION
• MORE ELECTRONS ANION

7
DIFFERENT AMOUNTS OF SUBATOMIC PARTICLES

• ISOTOPE different versions of the same element,
  all with differing amount of NEUTRONS

8
BIG IDEA!

• ENERGY
• LOSING AND GAINING ELECTRONS
• ELECTRON JUMPING
• REACTIONS WITH OTHER ATOMS
• SPITTING AND MANIPULATING ATOMS

9
NUCLEAR REACTIONS EXAMPLE OF FUSION H BOMB
10
FUSION FUSING OF ATOMS NUCLEI
11
EXAMPLE OF FUSION
12
FISSION- SPLITTING LARGE NUCLEI BY BOMBARDMENT OF
PARTICLES

14
ATOM BOMB

• Hydrogen bomb uses FUSION
• Atom Bomb uses FISSION
• H 1000 X more powerful than A

15
ELEMENTS

• AN ELEMENT IS A MATERIAL COMPOSED OF ONLY 1 TYPE
  OF ATOM!!!
• QUESTION HOW MANY TYPES OF ATOMS WOULD YOU FIND
  IN A PURE DIAMOND?

16
ENDOPLASMIC RETICULUM
