ok
this question is notin my answer key
can someone answer this?
I NEED ANSWERS!
Element 92 Uranium
In chemistry, a synthetic element is a chemical element that does not occur naturally on Earth, and can only be created artificially. So far 20 synthetic elements have been synthesized (those with atomic numbers 99-118). so the answer is the element Ensteinium with atomic number 99.
Americium (pronounced /ˌæməˈrɪsiəm/) is a synthetic element that has the symbol Am, the atomic number 95, and is used in smoke detectors.
The element with an atomic number of 112 is called Copernicium. It is a synthetic, radioactive element that can only occur in a laboratory.
The different atomic particles are:protonselectronsneutrons
Element 92 Uranium
It is natural. All elements with atomic numbers 92 and lower are naturally occurring.
Seaborgium
Radon, unless you count the synthetic Ununoctium. But because it is radioactive, highly unstable, and synthetic, I would discount it for now. It does however have the largest atomic mass for any known atomic substance. So, the answer is Radon.
All the synthetic elements on the Periodic Table appear after Uranium (atomic no. 92). These are the only synthetic elements.
The non-synthetic element that has the largest atomic mass is uranium, although it is radioactive. The atomic mass of uranium is 238.0289.
See the link bellow - chemical elements from atomic number 95 to atomic number 118.
Naturally occurring, Uranium. Synthetic, to be determined.

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.

Earthquakes are not 'atomic'. They are natural disasters.
