3. Do larger molecules have higher or lower boiling points than smaller molecules?

Higher

Lower

Size doesn\'t affect boiling point

It depends on which atoms are present

6. In the dot and cross diagram of the outer electrons showing the covalent bonding in a molecule of water (H₂O), how many electrons should be shown in areas 1, 2, 3 and 4?

There should be two electrons in each of areas 1 and 2, and zero electrons in areas 3 and 4.

There should be two electrons in each of areas 1 and 2, and two electrons in each of areas 3 and 4.

There should be two electrons in each of areas 1 and 2, and zero electrons in areas 3 and 4. There should also be an additional 4 electrons around the outside of the oxygen atom.

There should be four electrons in each of areas 1 and 2, and zero electrons in areas 3 and 4.

10. What is special about the elements in group 0?

They are all diatomic

They are very unreactive (because they have full outer electron shells)

They have the same number of electrons

They are all coloured gases
