The atoms

The atoms

1. The smallest particles of an element

   • Formed by
     • Neutrons
       • Don't have electrical charge
     • Electrons
       • Have negative charge
     • Protons
       • Have positive charge
   • Ion = electrically charged
     • (+) Cation
     • (-) Anion
   • Fission
   • Fussion

2. Bombs

   • ATOMIC ´Little Boy´ (Hiroshima)
   • HYDROGEN
   • FALLOUT
   • TACTICAL NUKES
   • M.A.D. (Mutually Assure Destuction)
   • ANTIMATTER

3. ATOMIC MODELS

   • DALTON
     • Billard ball model
       • Tiny, indivisible particles
   • THOMPSON
     • Plum Pudding model
       • Electrons in a positive atom
   • Rutherford
     • Rutherford's model
       • Discovered the nucleus
         • Nucleus = Protons & neutrons
   • Bohr
     • Planetary model
       • Electrons orbit around the nucleus
   • Leucippus & Democritus
     • 400 B.C. Concept of atom
   • Aristotle
     • 350 B.C. matter made of: water, earth, fire & air
   • Schrödinger
     • Electron cloud model
       • Electrons will be found on a certain area in a certain moment

4. Atomic number

   • Number of protons in the atom

5. Mass number

   • Number of protons & neutrons

6. Atomic mass

   • Average of the isoyopr'd masses

7. Isotopes

   • An atom is missing a or has an extra neutron

8. Neural atom

   • Same number of protons and electrons

9. Pure substances

   • Elements
     • 1 Type of atom
   • Compounds
     • 2 or more elements
