(a)
Interpretation:
The number of protons and electrons in aS8 molecule needs to be deduced
Concept Introduction:
- Every system found in nature is a composite of atoms, molecules, ions or other particles
- These are composed of fundamental subatomic particles: protons, neutrons and electrons.
- Each atom is characterized by two quantities:
Atomic number (Z) andatomic mass (A)
Z = atomic number = number of protons = number of electrons ------ (1)
A = atomic mass = number of protons + number of neutrons ------ (2)
For an ion: number of electrons = number of protons + charge on the ion ------ (3)

The monomers, ethylene glycol and terepthalic acid, are given. Add bonds and remove atoms as necessary to show the structure of a two repeat unit portion of a longer polymer chain of PET. You may need to zoom out to see the complete structure of all four monomer units.
