"Synthetic" could be another word for something that does not occur naturally.
Curium is a synthetic chemical element and does not occur naturally.
Synthetic materials like plastics, nuclear waste, and some chemical compounds are examples of things that do not occur naturally on Earth.
Silicone is a synthetic material made from silicon, oxygen, carbon, and hydrogen. It is created through a chemical process and does not occur naturally.
No, ecstasy (MDMA) is a synthetic drug derived from a compound found in certain plants. It does not naturally occur in the human body.

No. Americium is a synthetic element. It does not occur naturally on earth.
Transuranium elements are synthetic and do not occur naturally in significant quantities.
Silicone is a synthetic material made from silicon, oxygen, carbon, and hydrogen. It is created through a chemical process and does not occur naturally.
a synthetic element is not naturally found in the earth, they are handmade elements. OR elements that do not occur naturally and that are made in laboratories.
Plutonium is a synthetic element that is radioactive. It does not occur naturally in nature and must be artificially produced through the nuclear fission of uranium.
Americium is a synthetic element with the atomic number 95. It does not occur naturally on earth because it has a short half life and breaks down into other elements. It was first made by Glenn Seaborg in 1944 by bombarding plutonium with neutron. It was named Amercium after the Americas - because an element had already been named Europium after Europe.
No, ecstasy (MDMA) is a synthetic drug derived from a compound found in certain plants. It does not naturally occur in the human body.
No, most of the actinides do not occur naturally in Earth's crust. Actinides are a group of elements that are mostly synthetic or man-made through nuclear reactions. Only a few actinides, like uranium and thorium, occur naturally in significant quantities in the Earth's crust.
