Answer

Brief Explanations:

Atoms are the building - blocks of matter. The table shows physical properties of elements which are made of atoms. All substances in the universe are composed of atoms. For example, hydrogen atoms make up hydrogen gas, and different elements have distinct properties due to their unique atomic structures. These properties, like melting and boiling points and density, influence how elements interact and form compounds, which are essential for the existence of all matter in the universe.

Answer:

Atoms are the fundamental building - blocks of all matter in the universe. Their unique structures give elements distinct physical properties (such as melting point, boiling point, and density shown in the table), which determine how elements combine to form compounds and ultimately make up everything in the universe.
