WebScandium (Sc) is the lightest rare earth element. Scandium is present in crustal rocks in amounts greater than lead and precious metals, but it rarely occurs in concentrated quantities because it does not combine into common ores or minerals. WebSome of the most intriguing celestial observations are of the lightest elements: hydrogen (H), helium (He), lithium (Li), and the isotope of hydrogen known as deuterium ( 2 H; 1 proton and 1 neutron, often denoted D). We never measure less than about 23% of the mass of atoms being in 4 He, whether it is measured in stars, nebulae, or galaxies.
WebHydrogen is the lightest element. At standard conditions hydrogen is a gas of diatomic molecules having the formula H2. It is colorless, odorless, tasteless, [8] non-toxic, and highly combustible. Hydrogen is the most abundant chemical substance in the universe, constituting roughly 75% of all normal matter.
