Mass is defined as the amount of matter in an object while weight is defined as the force exerted by an object. SI unit of mass is kilograms while SI unit of weight is Newtons. Object weighing 1 kg mass will have 9.8 N weight.
So, in the above example of lead, its atomic number is 82 and that does not change; if it did, it would be a different element (thallium, atomic number 81, or bismuth, atomic number 83). The number of neutrons in the nucleus, as you may have gathered from the above example, can ...
