7 Terms

1
New cards

  • explain what is meant by electric current in metals

  • the movement of electrons

2
New cards

  • explain the structure of a metal

  • most electrons are fixed to their atoms + some electrons are free to move

  • metallic structure → lattice of positive ions surrounded by delocalised electrons

3
New cards

  • explain what is meant by electric current in electrolytes

  • the movement of ions

4
New cards

  • describe the structure an electrolyte

  • describe the decomposition of an electrolyte

  • molten or aqueous ionic solutions

  • separates into positive and negative ions → attracted to the cathode and anode

5
New cards

  • explain what is meant by conventional current

  • the representation of electric current as travelling from the positive to the negative terminal

6
New cards

  • describe the relation between electric current in metals and conventional current

  • travels from the negative to the positive terminal

  • opposite to the direction of conventional current

7
New cards

  • describe the relation between electric current in electrolytes and conventional current

  • can travel from the negative to the positive or from the positive to the negative terminal

  • either in the same direction or in the opposite direction of conventional current
