Well, first of all scientific hygrenals used by scientists made it easy to discover it.
Ernest Rutherford is the scientist who conducted the gold foil experiment in 1909, which led to the discovery that atoms contain a nucleus at their center. This experiment showed that the nucleus is small and positively charged, while the rest of the atom is mostly empty space.

Lead has more protons in the nucleus of its atoms compared to tin. Lead has 82 protons while tin has 50 protons in its nucleus.
There are 16 individual oxygen atoms contained in one mole of Li2C2O4.
Not just "most" atoms , but all atoms are composed of protons and neutrons, which are found in the nucleus, and electrons surrounding the nucleus in the electron cloud. And these atoms include gold.

british scientist discovered the nucleus
The nucleus was discovered in 1899.

Ernest Rutherford is the scientist who discovered that atoms have a positive charge. Through his gold foil experiment, he found that atoms have a small, positively charged nucleus at their center, surrounded by negatively charged electrons.
Ernest Rutherford is the scientist who conducted the gold foil experiment in 1911 and discovered that atoms have a small, dense nucleus at their center. This experiment led to the isolation and identification of the atomic nucleus.
Ernest Rutherford proved it with his famous gold foil experiment.
Scientists describe atoms as the basic building blocks of matter that make up everything in the universe. Atoms are composed of a nucleus containing protons and neutrons, surrounded by electrons in orbit. The properties of atoms are determined by the number of protons in the nucleus, which dictates the element the atom belongs to.
Ernest Rutherford, following the "gold foil" experiment.
Ernest Rutherford is the scientist credited with discovering the existence of the atomic nucleus, which is the center of an atom. His famous gold foil experiment in 1909 demonstrated that atoms have a dense, positively charged nucleus at the center surrounded by negatively charged electrons orbiting around it.
The scientist that suggested and proved that atoms contained a nucleus in which most of the weight of the atom was contained (in a very small volume) was Ernest Rutherford, in 1909. This was shown in the 'gold foil' experiment. This was made by shooting positively charged alpha particles, or a positively charged helium atom (2 protons, 2 nuetrons). these then when shot at the gold foil. some of the alpha particles just passed through the gold foil, but some were deflected. this proving that some hit the nucleus while others did not.
