Element mercury atomic mass
WebThe atomic mass is sort of an average of all of the different isotopes of an element. Mercury's atomic mass is 200.59, but we can round that to 201 (this is known as the mass number). This is a tally of the total number of particles in an atom's nucleus, so an 'average' atom of mercury contains 201 particles in its nucleus. WebMercury have boiling and melting points of 356.9 C and -38.87, respectively. It has atomic number of 80 and a molecular weight of 200.59 and belong to the Group 12 (Zinc group, II b) of the periodic table [2]. Chemical characteristics Mercury is highly poisonous.
