Electronic Structure and Balancing equations

Electronic Structure and Balancing equations

1. substance made of particles

   • called atoms
   • Proton=positive
     • electrical charge=+1
     • electron=negative
       • electrical charge=-1
     • neutron=neutral
       • electrical charge=0
       • Number of neutrons= mass number- atomic number= neutrons
         • example
         • Mass number>
         • Number of neutrons= 35-17=18
     • Number of protons & electrons=the same

2. atomic number ^

3. Electronic Structure

   • example
   • electronic structure= 2,8,8,1
