Relative Atomic Mass
A sample of lead contains 26.5% 206Pb, 26.5% 207Pb and 47% 208Pb, what is the relative atomic mass?
Why are there three different types of Pb atom?

He swapped Te and I. He did this because although they were no longer in mass order they better matched the properties of their new group. Later discovery of atomic number supported swapping them.
Thomson’s plum pudding model. He proposed a ball of positive charge with negative electrons spread out.
Rutherford’s nuclear atom. A central positive charge with negative electrons around it.
