WebIn 1860, scientists met at one of the first international chemistry conferences. They decided that hydrogen, the lightest element, be given a weight of 1. All other elements’ weights would be compared to that of a hydrogen atom. That means that if an element is eight times heavier than hydrogen, its weight is 8.
