Neon
Mercury is a metal element. Mass number of it is 201.
There are 120 neutrons in 202Hg. Mercury-202 has an atomic number of 80, which means it has 80 protons. Neutrons can be calculated by subtracting the atomic number from the atomic mass.
There isn't an element with the atomic number 202 because the known elements in the periodic table have atomic numbers up to 118, which is Oganesson. Any element with an atomic number higher than 118 would be highly unstable and would not exist naturally.
Atomic mass
The atomic mass (or weight) of silver is 107.8682 amu (atomic mass units)
Mercury is a metal element. Mass number of it is 201.
Platinum has six naturally occurring isotopes. They range from 190 to 196 in atomic mass. There are 31 synthetic isotopes in platinum that range from 166 to 202 in atomic mass.

Atomic no.=no. of protons Atomic mass=no. of protons+no. of neutrons Hence, atomic mass is greater
The atomic mass is the mass of a molecule, atomic particle or sub-atomic particle.
