Cl2 reacts with the element Sr to form an ionic compound. Based on periodic properties, identify a molecule, X2, that is likely to react with Sr in a way similar to how Cl2 reacts with Sr. Justify your choice.

Scrontium (Sr) is a metal in group 2 of the periodic table. While chlorine (Cl) is a nonmetal (halogen) in group 7 of the periodic table. Generally, elements in this two groups of the periodic table react together to form an ionic/electrovalent compound as illustrated in the question (shown below).

Sr + Cl₂ ⇒ SrCl₂

Because, members of group 2 react well with halogens to form an ionic/electrovalent compound, Sr can also react with iodine (I₂) or bromine (Br₂), any of which can be our X₂ (because the reactions are similar to that of how Cl₂ react), as shown below

Sr + I₂ ⇒ SrI₂

Sr + Br₂ ⇒ SrBr₂

A molecule, X₂, that is likely to react with Sr in a way similar to how Cl₂ reacts with Sr is F₂

Scrontium (Sr) is an Alkaline earth (i.e group 2) metal. It has 2 valence electrons and form bond by losing the two valence electrons.

Sr —> Sr²⁺ + 2e¯...... (1)

Chlorine (Cl) is a group 17 element (i.e Halogen). It has 7 valence electrons and form bond by accepting electron 1 to completely its octet configuration.

Cl + e¯ —> Cl¯.... (2)

Combining equation 1 and 2, we have

Sr + 2Cl + 2e¯ —> Sr²⁺ + 2Cl¯ + 2e¯

Cancel out 2e¯

Sr + 2Cl —> Sr²⁺2Cl¯

Sr + Cl₂ —> SrCl₂

NOTE: Group members has similar chemical properties. Therefore, other members of group 17 (i.e fluorine, bromine, iodine) can under go similar reaction with Scrontium (Sr).

For example Fluorine:

Sr —> Sr²⁺ + 2e¯...... (1)

F + e¯ —> F¯.... (2)

Combining equation 1 and 2, we have

Sr + 2F + 2e¯ —> Sr²⁺ + 2F¯ + 2e¯

Cancel out 2e¯

Sr + 2F —> Sr²⁺2F¯

Sr + F₂ —> SrF₂

Thus, fluorine molecule, F₂, will react with Sr in a way similar to how Cl₂ react.
