Mass number is the number of nucleons, (protons and neutrons) in the nucleus. The isotope Mercury-200 is stable and accounts for around 23% of naturally occurring mercury. The nearby elemnts thallium and gold do not have a stable isotope with mass number 200

Distinguish between the atomic number and mass number of an element?
The atomic number of an element is the number of protons in the nucleus of each atom of the element. Mass number is a property of a particular isotope of the element rather than of the element itself: The mass number is the sum of the numbers of protons and neutrons in the nucleus of each atom of the isotope.
What is the mass of an element?
The mass number of an element is the atomic mass rounded to the nearest whole number. For Example, if the atomic mass is 54.94 (Manganese [Mn]), then the mass number will be 55. You can use the mass number to calculate the amount of neutrons in an isotope.
