Understand the question is asking about the scope of elements shown in the periodic table.
Recall that the periodic table is a comprehensive chart that organizes all known chemical elements based on their atomic number and properties.
Recognize that the periodic table includes metals, nonmetals, metalloids, naturally occurring elements, and synthetic elements created in laboratories.
Therefore, the periodic table displays all known chemical elements, not just a subset like only metals or only naturally occurring elements.
Conclude that the best completion for the statement is 'All' because the periodic table includes every known element.
