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.
The factors playing into the strength of an ion's charge density are therefore the charge of the ion (e.g. 2+ for Mg, 1+ for Na) and the effective volume which that charge acts over - which is where the ionic radius comes in. (Note this is different to atomic radius.) Charge density = charge/volume As the magnesium ion and sodium ion both have the same electronic configuration i.e. that of neon (because Mg has lost 2 electrons and Na has lost 1 and they now both have 10 electrons in total) the charge of the electrons around the ions is the same. But - magnesium has one more proton in its nucleus.
