No, since there is little or no free hydrogen on Earth. (plenty in the sun, and it is a natural resource there.)
There is bound hydrogen on Earth (mostly water), but the energy required to extract it is greater than the energy it gives up in burning.
Boron is a naturally occurring element found in the Earth's crust. It is not a synthetic material.
Helium is a natural element that is extracted from underground gas deposits through a process called helium mining. It is not synthetic, but rather a naturally occurring element found in the Earth's crust.
Phosphorus is an element. It's natural.
The artificial element with atomic number 99 found in the debris of the hydrogen bomb in 1953 is einsteinium (Es). It is a radioactive synthetic element that is created in nuclear reactors and has no known natural occurrence on Earth. Einsteinium was named after Albert Einstein.
No, aluminum is a naturally occurring chemical element and is the most abundant metal in the Earth's crust. It is not a synthetic element, meaning it is not artificially created by humans.
Yttrium is a natural element found in the Earth's crust. It is not a synthetic element.
Lithium is a natural element that is found in various minerals and salts in the Earth's crust. It is not a synthetic element.
Cadmium is a natural chemical element.
Boron is a naturally occurring element found in the Earth's crust. It is not a synthetic material.
Helium is a natural element that is extracted from underground gas deposits through a process called helium mining. It is not synthetic, but rather a naturally occurring element found in the Earth's crust.
Yes
Aluminium is a natural chemical element.
Francium is a natural chemical element.
Phosphorus is an element. It's natural.
No, boron is a naturally occurring element that is found in the Earth's crust. It is not synthetic.
Yes, xenon is a naturally occurring element found in trace amounts in the Earth's atmosphere. It is not a synthetic element.
no, both natural and synthetic rubber are polymers
