# Problem: Arranging elements by atomic number reveals a periodic pattern of properties. This pattern is the basis of the periodic table.If F is a reactive nonmetal, which other element or elements shown here do you expect to also be a reactive nonmetal?

###### FREE Expert Solution

We’re asked to determine which other element or elements shown in the diagram is/are expected to also be a reactive nonmetal if F is a reactive nonmetal based on the periodic pattern of properties in the Periodic table.

From the diagram, we can see that elements with even atomic numbers starting from He (2) to the next 8th elements are non-reactive, while elements with odd atomic numbers immediately after the non-reactive elements are reactive.

This means that if F with the atomic number = 9 (odd number) is a reactive non-metal, then:
