Mg2+Cl−Cl− (4.3.2) (4.3.2) Mg 2 + Cl − Cl −. Now the positive and negative charges are balanced. We could write the chemical formula for this ionic compound as MgClCl MgClCl, but the convention is to use a numerical subscript when there is more than one ion of a given type— MgCl2 MgCl 2.
Under normal conditions, molecular compounds often exist as gases, low-boiling liquids, and low-melting solids, although many important exceptions exist. Whereas ionic compounds are usually formed when a metal and a nonmetal combine, covalent compounds are usually formed by a combination of nonmetals.

Figure2.7.3 2.7. 3: Example of some compounds that have multiple oxidation states. Note mercury (1) is not a monoatomic cation, but is really a homonuclear diatomic ion of two mercury atoms bound to each other, both having lost one electron. So Hg 2 Cl 2 it the lowest whole number ratio of cation to anion. Example 2.

Because the ionic compound must be electrically neutral, it must have the same number of positive and negative charges. Two aluminum ions, each with a charge of 3+, would give us six positive charges, and three oxide ions, each with a charge of 2−, would give us six negative charges. The formula would be Al 2 O 3.

This results in the formation of magnesium acetate and water. The reaction can be written as follows: MgCO 3 + 2CH 3 COOH → Mg (CH 3 COO) 2 + H 2 O. Or. Mg (OH) 2 + 2CH 3 COOH → Mg (CH 3 COO) 2 + 2H 2 O. The product of this reaction, magnesium acetate, tends to form a tetrahydrate in an aqueous solution, denoted as Mg (CH 3 COO) 2 · 4H 2 O.
