Solution

Solution Steps

Step 1: Determine if Hydrogen and Iodine Form a Molecular Compound

Hydrogen (H) and iodine (I) are both nonmetals. Nonmetals typically form molecular compounds through covalent bonding. Therefore, hydrogen and iodine will form a molecular compound.

Step 2: Determine the Chemical Formula and Name for Hydrogen and Iodine

The simplest molecular compound formed by hydrogen and iodine is hydrogen iodide, with the chemical formula HI.

Step 3: Determine if Nitrogen and Fluorine Form a Molecular Compound

Nitrogen (N) and fluorine (F) are both nonmetals. Nonmetals typically form molecular compounds through covalent bonding. Therefore, nitrogen and fluorine will form a molecular compound.

Step 4: Determine the Chemical Formula and Name for Nitrogen and Fluorine

The simplest molecular compound formed by nitrogen and fluorine is nitrogen trifluoride, with the chemical formula NF$_3$.

Step 5: Determine if Calcium and Bromine Form a Molecular Compound

Calcium (Ca) is a metal, and bromine (Br) is a nonmetal. Metals and nonmetals typically form ionic compounds, not molecular compounds. Therefore, calcium and bromine will not form a molecular compound.
