Atoms, one simple word
Building a tower of magnetic blocks is a physical change because the blocks are simply being rearranged without any chemical reactions taking place. The properties of the blocks themselves remain the same.
Condensation
the building blocks of substances are called what atoms or molecules?
Antoine Lavoisier developed the modern definition of a chemical element by recognizing that elements cannot be broken down into simpler substances through chemical means. He conducted numerous experiments to determine the conservation of mass during chemical reactions, leading to the concept of the conservation of matter and the identification of elements as the basic building blocks of matter.
The tuna sandwich would be broken down into its chemical building blocks, such as proteins from the tuna, carbohydrates from the bread, and fats from any mayonnaise or other ingredients. These building blocks would then be used by the body for energy, repair, and growth in various cells and tissues.
Helium is an element. By definition, elements are the most basic building blocks of matter. Therefore, the only chemical in Helium would be Helium.

The universe building blocks are chemical elements. (I use Switched on Schoolhouse and this is the answer.) hope this helps :)
Proteins are the macromolecules that provide building blocks for tissues and help regulate chemical reactions in the body. They are made up of amino acids that serve as the building blocks for building muscle, skin, and other tissues, and they also act as enzymes that catalyze chemical reactions in the body.

Amino acids, using the peptide bond.
