It was the first genocide carried away on the Hispaniola. The Native Americans people were drastically wiped out. In 1942, the population was estimated about 8,000,000. In the year 1942, Christopher Columbus, the explorer from Italy sailed 3 old ships to land up in India. Although there was Marco Polo and Norsemen who already sailed years before but no sailor wanted to sail for the unknown places.
Lithium is a Group IA metal, so its ion will have a +1 charge. Phosphate is a polyatomic ion with a -3 charge. The compound needs three lithium ions to balance the -3 charge of the phosphate, so the formula is Li 3 PO 4. Notice that we didn't do anything with the 4 subscript on the phosphate.
Phosphate has a charge of 3-, so we will have 3 magnesium cations. We end up with our final formula: Mg3(PO4)2. Ions are not in parentheses unless they are polyatomic, and there is more than one of the polyatomic ions. This is why the NO3 in NaNO3 is not in parentheses, and in parentheses in Mg(NO3)2.
