Step 1:: Understand the question
The question asks us to fill in the blank with one of the options given. The blank refers to a property that can vary within a family on the periodic table.
Step 2:: Identify the correct answer
In a family on the periodic table, elements have similar properties due to their similar electron configurations. One such property that can vary within a family is reactivity.
Step 3:: Explain the answer
Reactivity refers to the ability of an element to combine with other elements to form compounds. In a family on the periodic table, reactivity can vary due to changes in the number of valence electrons or the atomic radius. For example, in the alkali metal family, reactivity decreases as you move down the group due to an increase in atomic radius and a decrease in ionization energy.
Final Answer
Reactivity varies in a family on the periodic table.
