Put the following elements into five pairs of elements that have similar chemical reactivity: F, Sr, P, Ca, O, Br, Rb, Sb, Li, S

Elements with the same chemical reactivity will belong to the same group on the periodic table. This implies that elements in the same column will have the same reactivity;

Li and Rb are both alkali metals in group 1

Ca and Sr are both alkali earth metals in group 2

F and Br are halogens in group 7

O and S are group 6 elements

P and Sb are both in group 5 on the periodic table

So these groupings show elements with the same chemical properties.

The following elements can be put into five pairs of elements that have similar chemical reactivity in the following ways: F and Br, Sr and Ca, P and Sb, O and S, Li and Rb.

The periodic table shows and displays the tabular arrangement of atomic elements as they are categorized into groups and periods. Elements in the same groups exhibit certain chemical properties and reactivity with one another.

On the periodic table;

Fluorine F and Bromine Br are elements of the halogen family. They are highly electronegative in nature and exhibit similar reactivity.
Sr and Ca are alkaline earth metals. They are found in group two (2). Their oxidation state is +2
P and Sb are located on group 5 of the periodic table and they tend to share some similar chemical reactivity.
O and S are nonmetals and they can be found in group 6 with -2 oxidation state.
Li and Rb are alkali metals, they form ionic bonds with the halogen family.

Therefore, we can conclude that we've fully understood the concept of how chemical reactivity works with elements that are grouped in the same group.
