Atomic Structure and The Periodic Table

Atomic Structure and The Periodic Table

1. Structure of an atom

   • Name And Charge
     • Electron, Negative Charge
     • Protons, Postive Chatge

2. Structure of an Atom

   • Name and Charge
     • Electrons, Negative Charge
     • Protons, Positive Charge
     • Neutrons, No Charge
   • Atomic Mass
     • Protons
       • +1
     • Neutrons
       • +1
     • Electrons
       • 0
   • Nucleus
     • Protons + Neutrons

3. Atomic Mass/ Number

   • Atomic Mass
     • Proton + Neutron
   • Atomic Number
     • Number of Protons, which equal the number of Electrons

4. Isotopes

   • Isotopes are different atoms of an element with the same number of protons and electrons but different numbers of neutrons
   • Example:
     • There are two isotopes of copper, 69% of copper is CU-63 and 31% of copper is CU-65 the relative atomic mass of copper. Give your answer to 1 decimal place.
       • CU-63= 60% CU-65= 31%
         • (69*63) + (31*65) (69+31)
           • =63.6

5. Ionic Bonding

   • Ion
     • An ion is an atom or group of atoms, with a positive or negative charge. Because they have gained or lost electrons
   • Positively charged ions are called Catons
   • Negatively Charged ions are called Anions
