Periodic Table

For the first time in history, drastic changes will be made to the atomic weights of 10 elements in the periodic table. In nature, many elements exist as isotopes such that the same element can have different atomic weights. The International Union of Pure and Applied Chemistry announced that the atomic weights of these elements will now be expressed as intervals, as opposed to the customary single value, to reflect the variation in atomic weight. Though tedious to correct all periodic tables found worldwide, these changes are important in research and the industry and is evidence of advances made to better understand the world that surrounds us. But don’t worry, these changes won’t affect your body weight.
