  1. 1What atoms do covalent bonds occur between?
    1. ANon-metal atoms
    2. BMetal atoms
    3. CMetal and non-metal atoms
  2. 2A single covalent bond is formed when two atoms share one pair of electrons
    1. ATrue
    2. BFalse
  3. 3How many electrons are shared when a double bond is formed?
    1. A2 electrons
    2. BTwo pairs
    3. C1 pair
    4. D12 electrons
  4. 4What is each atom aiming to do when sharing it's electrons?
    1. AGet a full outer shell
    2. BLose all of its neutrons
    3. CGive away all of it's electrons to other elements
    4. DShare with all it's friends to make the world a happier place
  5. 5What are the properties of a simple covalent molecule? (2)
    1. AWeak forces between the molecules
    2. BStrong covalent bonds between atoms
    3. CWeak covalent bonds between atoms
    4. DStrong forces between the molecules
  6. 6Simple covalent molecules have high melting and boiling points and can conduct electricity
    1. ATrue
    2. BFalse
  7. 7What makes the giant molecule different to a simple molecule?
    1. AMany of the atoms in a giant molecule are joined together covalently throughout the whole giant molecule structure
    2. BThere are more electrons in the atoms of the giant molecules which makes them negatively charged and able to conduct electricity
    3. CGiant molecules have high boiling and melting points, simple molecules have low ones
    4. DA simple molecule is made by breaking the atoms apart, a giant molecule is made by connecting atoms together manually

    1. AStrong?
    2. BWeak?
  10. 10What methods can you use to test different compounds?
    1. AMelting them using a bunsen burner
    2. BPlacing electrodes into a sample of the substance to see if it conducts electricity as a solid, liquid or aqueous solution
    3. CTiming how long it takes the substance to dissolve in water
