What is the first element in the periodic table?
Hydrogen: represented on the table with by the symbol HIt has the lightest atomic weight of all elements at 1.00794Hydrogen is the most abundant chemical element, constituting roughly 75% of the universe's elemental mass.
What is the name of the lightest element on the periodic table How and who discovered it?
Hydrogen is the lightest element on the periodic table. Henry Cavendish collected Hydrogen by placing Zinc in an acid and originally called it inflammable air. However, Paracelsus of Switzerland had noticed 250 years before that Iron placed in acid gave off a gas and that gas would burn: but did not study it further.
