Answer:
S–34
Step-by-step explanation:
From the question given above, the following data were obtained:
Neutron number = 18
The isotope of sulphur still retains its atomic number of 16.
Recall:
Atomic number = proton number
Atomic number of sulphur (S) = 16
Therefore,
Proton number = 16
Next, we shall determine the mass number of the sulphur isotope. This can be obtained as follow:
Proton number = 16
Neutron number = 18
Mass number =.?
Mass number = Proton + Neutron
Mass number = 16 + 18
Mass number = 34
The symbol for sulphur is S.
Thus, the symbol of sulfur isotope that contains 18 neutrons is S–34
