Where did elements on the periodic table come from?

Answer 1

Everything on and within the Earth, including the molecules that make up you, me, and everyone we have ever heard about and that will ever be, came from the heart of ancient stars, which more than 5 billion years ago exploded in interstellar space. That matter eventually coalesced into our Solar System. Some of it became our sun, some of it wanders our solar system as asteroids, and some of it formed a planet that would be called Earth. We are star dust.

Answer 2

Basically, elements are created by stars through fusion (stellar nucleosynthesis). The most abundant element in the universe is hydrogen, and most of it is thought to have been around at the beginning of time. Big Bang or not, the universe is expanding, and hydrogen was around at the beginning and is still around now in large quantity. A "cloud" of hydrogen in large quantities and (perhaps) other elements in smaller quantities is gravitationally "gathered" into a quantity sufficient to create a star. The star will begin burning by fusion after sufficient materials have been pulled into a gravity well and all the "stuff" heated by compression to the point of ignition. The star spends the rest of its life making heavier elements from lighter ones. That's stellar nuclear synthesis. Finally, a star (of the right kind) reaches the end of its life and it goes supernova. When this happens, all the elements heavier than those created by "regular fusion" in the star are created by the massive force of compressive collapse, and then the blast flings the material outward.

Answer 3

Hydrogen, a little helium and less lithium were created in the big bang. The universe is about 95% hydrogen. Clouds of hydrogen gas and dust are compressed by gravity into stars, which, by the process of nuclear fusion, change a one-proton hydrogen nucleus into a two-proton helium nucleus. When the star's core runs out of hydrogen, the nuclear reaction pauses, and gravity compresses the star, heating it up enough to fuse helium. If the star is big enough, it can eventually create all the elements in the periodic table up to iron...a star can't fuse iron: the reaction uses up more energy than it releases. At that point, a giant star explodes as a supernova, which releases enough energy to make all the elements heavier than iron.

Answer 4

All the elements on the Periodic Table are created by stars in our universe. Stars recycle these elements to make new stars and they make new elements. Without stars, there would be no periodic table of elements.

Answer 5

It comes from English or Latin words for the elements or related substances which then makes the letter from the word, making it a element symbol.
