ATOM

ATOM

1. Is

   • The smallest unit in which you can divide matter without lose your chemical properties

2. STRUCTURE

   • It consists of
     • Protons
       • That has
         • Positive charge
     • Electrons
       • That has
         • Negative charge
     • Neutrons
       • That has
         • Neutral charge (no charge)
     • Atom nucleus
       • Formed by
         • Protons and neutrons that in set it they call nucleons
     • Quarks
       • The protons and the neutrons are composed of a pair of particles called quarks and gluons
         • Gluons
           • They are
             • responsible for joining to the quarks with each other.
         • Neutrons
           • They contain
             • A quark ascending and two descending quarks
         • Protons
           • They contain
             • Two ascending quarks of positive charge (+2/3) and a descending quark with negative charge (-1/3)

3. THE ATOMS AND THE PERIODIC TABLE

   • It's divided in
     • PROTONS
       • Is equal to
         • Number atomic. represented with the letter Z
     • ELECTRONS
       • Is equal to
         • Atomic number
     • NEUTRONS
       • Is the
         • Rounded atomic mass - atomic number

4. ATOMIC MODELS

   • They are
     • ATOMIC MODEL OF JOHN DALTON (1803)
     • ATOMIC MODEL OF JOSEPH JOHN THOMSON
     • ATOMIC MODEL OF RUTHERFORD
     • ATOMIC MODEL OF BOHR
     • ATOMIC MODEL OF SOMMERFELD
     • ATOMIC MODEL OF SCHRODINGER
