What are the main elements in common construction materials like steel and concrete, and what are their atomic numbers?

The atomic number is equal to the number of protons in an atom's nucleus. Hydrogen's atomic number is 1 because all hydrogen atoms contain exactly one proton. To detect y-rays efficiently, a material with a high density and high effective Z (number of protons per atom) is required. Inorganic scintillation crystals ...
