Answer:
The bromine molecule, represented as Br2, is expected to interact with Sr in a manner akin to the chlorine molecule, Cl2.
Explanation:
Chlorine is found in group 7 of the periodic table, known as the halogens, where its molecular formula is Cl2. Bromine follows chlorine in the same group, yielding the molecular formula Br2. Due to their analogous characteristics, bromine is likely to react with Strontium similarly to chlorine.
Elements within the same group share comparable chemical traits because they possess an identical number of valence electrons. Both chlorine and bromine are in group 7 and each has seven valence electrons. Though chlorine is more reactive and thus has a more vigorous reaction with metals, both elements ultimately react to form salts, developing negatively-charged ions with a -1 charge.
Reactions of Strontium with halogens include:
With chlorine: Sr + Cl2 ---> SrCl2
With bromine: Sr + Br2 ---> SrBr2
These resulting salts are crystalline in nature, exhibiting high melting and boiling points.
