Rutherford's scattering experiment

Rutherford’s scattering experiment is also known as the gold foil experiment. This experiment disproved the plum pudding model of J.J. Thomson. In a gold foil experiment, high-energy alpha particles are made to strike a thin gold foil. The scattered alpha particles are detected using a detector. This experiment showed that the positive charge of the atom is at the center. Most of the atom’s mass is also confined to a small volume at the center. This region is known as the nucleus of the atom.

Question

Elements that appear in the same column of the periodic table
often share similar chemical properties. In the case of the
alkaline earth metals, this is troublesome since the body treats
calcium (necessary for proper bone growth) and radium (a
radioactive element) as chemically similar, storing both in
bone marrow. The radium then bombards nearby bone cells
with alpha particles, causing them to "crumble."
Ionized
Radium poisoning investigations often center on the
identification of radium and its isotopes in bone samples using
