The method of determining the most common isotope of lead is by determining the average atomic mass. The formula for determining the average atomic mass is:
Substituting the values in the formula:
The most common isotope of lead is:
Lead - 207.22 amu
The atomic symbol of lead is 
. The atomic number of is 82.
So, the the most common isotope of lead can be written as:
and Lead - 207.22 amu.
Saturated hydrocarbons consists of C-C single bond whereas Unsaturated hydrocarbons consists C-C double/triple bond.
