Yes, curium is a manmade element produced through nuclear reactions. It was first synthesized in 1944 by researchers at the University of California, Berkeley, as part of the Manhattan Project.
Mendelevium is a manmade element and does not occur naturally in nature. It is produced by bombarding einsteinium with alpha particles in a particle accelerator.
Gold is a natural element. It is normally found as a solid metal and is relatively rare and expensive.
Dacron is a manmade synthetic fiber, which is a type of polyester. It is not a natural fiber like cotton, wool, or silk. Dacron is known for its durability and resistance to wrinkles and stretching.
