Density = Mass / Volume
Density = 2.74g / 3.10cm³
Density = 0.88 g/cm³
the second one is equal and opposite
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.
A positive change atom of hydrogen-ion. A normal hydrogen atomic nucleus
