Question

1. which pair of elements is most likely to form a molecular compound with each other? aluminum (al) & oxygen (o) potassium (k) & lithium (li) magnesium (mg) & iodine (i) sulfur (s) & fluorine (f) bromine (br) & barium (ba)

Explanation:

Molecular compounds form between non - metals. Sulfur (S) and Fluorine (F) are both non - metals.

• Aluminum (Al) is a metal and oxygen (O) is a non - metal. They form an ionic compound (aluminum oxide, \(Al_2O_3\)).
• Potassium (K) and Lithium (Li) are both metals. Metals do not form molecular compounds with each other.
• Magnesium (Mg) is a metal and iodine (I) is a non - metal. They form an ionic compound (magnesium iodide, \(MgI_2\)).
• Bromine (Br) is a non - metal and barium (Ba) is a metal. They form an ionic compound (barium bromide, \(BaBr_2\)).

Answer:

Sulfur (S) & Fluorine (F)
