How do polyatomic ions form compounds?

Answer 1

Ionic bonds to positively charged ions known as cations create an electrostatic attraction that holds covalent compounds, or poly atomic ions, together because they have an overall charge.

With the exception of ammonium, #NH_4^+#, these ions carry a negative

Examples include sulfate, #SO_4^-2#, nitrate, #NO_3^-#, and phosphate, #PO_4^-3#.

If we consider nitrate it will form one ionic bond with cation , such as sodium that has + one charge. The formula is #NaNO_3#

If nitrate bonds with calcium, two nitrate ions each with one calcium ion, #Ca(NO_3)_2#

If nitrate bonds with aluminum which has a plus three charge, three nitrates are required to create an ionic compound, #Al(NO_3)_3#.

Polyatomic ions form compounds by combining with other ions or atoms through ionic bonding or covalent bonding. They have a specific charge due to the arrangement of their atoms, which allows them to combine with oppositely charged ions to form stable compounds.

When evaluating a one-sided limit, you need to be careful when a quantity is approaching zero since its sign is different depending on which way it is approaching zero from. Let us look at some examples.
