As you have specifically asked answers for the questions 27-34, I have solved them as below.
27) Protons - positive charge
28) Neutrons - no electric charge
29) Electrons - negative charge
30) Results from unequal sharing of electrons - polar covalent bond
31) Results from equal sharing of electrons - no polar covalent bond
32) Are involved in chemical reactions - outer electons
33) Electrons being transformed from one atom to another - ionic bond
34) Explain the attraction of water molecules to each other - hydrogen bond
