elements after uranium (atomic number 92) are all artificially made.
No, only the elements up to Uranium (Z=92) occur naturally on Earth. The rest have only been made synthetically, because of their radioactivity which renders them unstable and thus unable to exist naturally. The synthetically made elements are called transuranic elements.
Yes, it is.
It means man-made.
no, unless it is not
No. There are twenty elements that can only be produced synthetically.
If it's made synthetically, then it's no longer "Olive oil" -There is NO substitute for real virgin olive oil.
Copper occurs natually, it is one of the Elements of the Periodic Table. It's found in crystal-like pieces, with copper ore.
E151 is an azo dye and is made synthetically.
it is naturally found
It was the first synthetically (chemically) made fabric. Before then, people had to use cotton and wool. It was the first synthetically (chemically) made fabric. Before then, people had to use cotton and wool.
Some of the elements on the Periodic Table are Radioactive. This means that their nuclei decay to form other elements in a decay chain. There are currently 33 known radioactive elements of which 20 are currently produced synthetically.
