Sulfur is a Group VI element. A sample of sulfur contains two isotopes, $$\({ }^{32} \mathrm{~S}\)$$ and $$\({ }^{34} \mathrm{~S}\)$$. (i) Complete Table 5.1 to show the number of protons and neutrons in one atom of each isotope of sulfur. (ii) State why these isotopes have identical chemical properties. ................................................................................................................................... (iii) State the mass of $$\(6.02 \times 10^{23}\)$$ atoms of $$\({ }^{34} \mathrm{~S}\)$$. Include units in your answer. ................................................................................................................................... (iv) State the name of the amount of substance which contains $$\(6.02 \times 10^{23}\)$$ atoms. ................................................................................................................................... (v) Table 5.2 shows the relative abundance of these isotopes of sulfur in the sample. Calculate the relative atomic mass of sulfur in this sample to one decimal place. relative atomic mass $$\(=\)$$ ..........................
