Web5 de abr. de 2024 · The earliest known important chemical property of hydrogen is that it burns with oxygen to form water, H 2 O; indeed, the name hydrogen is derived from Greek words meaning “maker of water.” WebThe first element produced would be hydrogen. Giant clouds of these primordial elements would then form stars and galaxies. Other elements were formed by fusion within the stars. All heavy atoms (metals) were formed in stars, by fusion, billions of years before out planet even existed! Inorganic elements (and you!) are made of star stuff.
