An example is when on a seesaw if a kid is on one side and an adult is on the other then it is unbalanced because the adult weighs more
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.
Answer:
