4.Science What is the atomic weight of the lightest element on the periodic table?

For each element the atomic weight is on the periodic table right under the symbol of the element. The carbon atomic weight is 12 units of atomic mass (amu), so the weight of one mole is 12 grams. A sample consisting the atoms of a single element, weights the sample in grams and separates the element by its atomic weight.

5.Science What is the atomic weight of the lightest element on the periodic table?

Hydrogen is a chemical element with atomic number 1 which means there are 1 protons and 1 electrons in the atomic structure.The chemical symbol for Hydrogen is H. With a standard atomic weight of circa 1.008, hydrogen is the lightest element on the periodic table. Its monatomic form (H) is the most abundant chemical substance in the Universe, constituting roughly 75% of all baryonic mass.
