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).

Scientists use scanning tunneling microscopy to understand how a material's electronic or magnetic properties relate to its ...

However, one proton is about 1,835 times more massive than an electron. Atoms always have an equal number of protons and electrons, and the number of protons and neutrons is usually the same as well.
