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.
What is the electrical charge of a hydrogen atom? All atoms have no charge. Their charge is zero. Theyâre charge-neutral. There is exactly the same number of electrons and protons in an atom. Electrons have a charge of â [math]-e[/math] â and protons a charge of â [math]e[/math] â, where [math]e[/math] is the elementary charge and is [math]1.60217662 Ã 10^{-19}[/math] coulombs. So their charges cancel out. For hydrogen, it has 1 proton and 1 electron. (Atoms can also lose some of their electrons, thus becoming ions, which do have a charge.) _____
