Answer:
A flame test of a colorless solution gives a bright yellow color. When reacted with AgNO, a white precipitate forms that dissolves when HNO, is added.
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.
