For each row in the table below, decide whether the pair of elements will form a molecular or ionic compound. If they will, then enter the chemical formula of the compound. If the elements will form more than one compound, enter the compound with the fewest total number of atoms. You may assume all chemical bonds are single bonds, not double or triple bonds. element #1 nitrogen oxygen magnesium element #2 compound formed? chemical formula O ionic O molecular O neither bromine fluorine oxygen O O O O O O O O O O ionic O molecular O neither O ionic O molecular O neither X S

Now that we have a reference for many of the common polyatomic ions, let's look at how to write the chemical formulas for compounds that contain them. There are two main things to keep in mind:   If a compound contains more than one polyatomic ion of the same type, we need to place parentheses around the ion's formula beforeusing a subscript to indicate how many ions of that type are in the compound.   The overall charge for the ionic compound must be neutral, which means the sum of the charges from the cations and anions should add up to zero.We can use this rule to figure out the formula of an ionic compound when we know the charge on the anion and the cation. This rule can also be useful for deducing the charge of an ion when the chemical formula for the ionic compound is known.   Example: Write the chemical formula for calcium hydroxide (calcium and hydroxide). Calcium is an alkaline earth metal in Group 2 on the periodic table, so it forms ions with a 2+ charge. From our table…
