... An empirical formula gives the relative numbers of atoms of each element present in a chemical compound. For example, the formula NaCl, indicates that in this compound there is one Na atom for every Cl. In H2O there are two hydrogen atoms for every oxygen atom. By now you may have learned how to wri ...

... call the magnetic poles. The magnetic field is strongest at the two poles. Our Earth is like a great big magnet, and the magnetic force is strongest near the North Pole and the South Pole. The ends of magnets are also called the north and south poles. This is the law of magnetic force: Unlike poles ...
