Structure of the Atom

Structure of the Atom

1. Atoms are the smallest parts of an element that can take part iun a chemical reation

2. The atom is made up from three subatomic particles.

   • Proton
     • Charge of +1
     • Relative mass of 1
     • Found in the nucleus with the netron
   • Neutron
     • No Relative charge
     • Relative mass fof 1
     • Found with the Proton in the nucleus
   • Electron
     • Relative mass of 0.0005
     • Relative charge of -1
     • Whizzes around the outside of the necleus

3. When an atom has thesame number of protons as electrons it has a charge of 0

4. Compound

   • Two or more elements that have been cheically bonded together
     • Ion
       • Positive
         • Sodium ion
       • Negative
         • Chloride ion
       • Ions are electrically charged particles formed when atoms lose or gain electrons.
       • Metals
         • Metals lose electons
           • Posative
       • Non metals
         • Non metals gain electrons
           • Negative

5. Element

   • A substance that consist of only one type of atom

6. Isotopes

   • Atoms with the same number of protons but a different number of neutrons
   • They have more relavtive mass
