Manmade elements.
These have traditionally been considered to be: Technetium, Promethium, Neptunium, and all elements beyond Neptunium.
However trace levels of several of these have since then been detected naturally.

How do you use the laboratory?
If in chemistry laboratory then chemists can analyse compounds and elements to detemine concentration or if it does exist in the compound. or molecules for medicine, fertilizers, new materials are made and also measurement of energy in bonds and measursment of constants. In a physics lab they measure waves, strength of materials and forces In a biology lab they look at living cells and diseases with cures.
How many currently elements?
There are 92 elements that exist in nature*. Every heavier element has decayed before our time. Of course, there are more elements in the periodic table, but they are all synthetic elements-they were made in a laboratory. Theoretically, there is no limit on how heavy an element could become-you can always add a proton to the nucleus. However these synthetic elements exist only for a fraction of a second and only in particle accelerators. There are currently 115 known elements.
How are transgenic organisms made?
Via laboratory procedures.
Can auxins be produced naturally or can they be made in a laboratory?
true
How were the heavy elements from iron to uranium made?
Up to uranium elements are made by stellar nuclear synthesis; after uranium elements are man made.
How many elements are made only in a laboratory?
How many radioactive elements are made only in a laboratory?
Are some elements that have been made by scientists under laboratory?
Yes, Some elements that have been made by scientists under laboratory.
From naturally occurring of laboratory-made elements it is possible to make hundreds of thousands of oxygen?
from naturally ocurring or laboratory-made elements, it is possible to make hundreds of thousands of_______________
Are some elements have been made by scientists under laboratory conditions?
Yes
What are elements called that are created by main in a laboratory?
Synthetic or man-made elements. Obviously synthetic sounds significantly cooler.
How Many Radioactive Elements Are Made in the Laboratory?
About 28 elements were discovered in the laboratory. But after the man made preparation some elements were discovered also in nature in very extremely traces: Pm, Tc, Pu, Np, Am, Cm, Bk.
How can new elements be made in the laboratory?
Yes, but you need exceptionally expensive and complex nuclear installations.
Compare the role of nuclear fusion in the formation of Earth's naturally occurring elements and in the creation of synthetic elements in the laboratory?
Creation of synthetic elements in the laboratory is not based on nuclear fusion.
What can be made in the field or in the laboratory?
A hypothesis
What are elements that are made in lab called?
Synthetic is the term you are looking for i believe.
What is the meaning of Laboratory apparatuses?
The devices used in the laboratory during the experiments held and during the chemical combination of different elements are known as "laboratory apparatuses"
What is a good example of a designer virus?
A designer virus is a man-made virus synthesized by piecing together the genetic elements in a laboratory. One good example is synthetic poliovirus created to study the infection in laboratory animals.
