Some man-made elements are stable, while others are not. Stability of an element depends on its structure and nuclear properties. Elements beyond uranium on the Periodic Table tend to be less stable, with some being highly radioactive and decaying quickly.

What man made element has 148 neutrons?
There are a couple elements who could have isotopes with 148 neutrons. The most stable isotopes of both americium and plutonium have 148 neutrons.
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.
Are the synthetic elements true elements?
Yes, they are true chemical elements but man made.
Are diatomic elements stable when in molecular form?
Yes, these chemical elements are stable.
Are most elements man made or natural?
Most elements are naturally occurring in the universe, with only a small percentage being man-made through processes like nuclear reactions in laboratories.
How do you make man made elements?
Man-made elements are made in a particle accelerator.
If they are man made then how are they elements?
Examples of man made elements: curium, californium, bohrium, mendelevium, nobelium etc.
What man made element has 148 neutrons?

How many are man made elements of the 118 known elements?
The 26 transuranic elements (elements with atomic numbers higher than 92) are man-made. Some lists also count technetium (element 43) as man-made as well. --------------- Now (January 2013) 97 chemical elements are considered as natural and 21 as man made.
5 man made elements of lights?

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.
Are the synthetic elements true elements?
Yes, they are true chemical elements but man made.
How many man made elements are in the periodic table?
Out of the 112 elements known, 90 are found in nature and the rest (22 are man made).
When elements are stable?
Elements are stable when they have completely filled (or half filled) orbitals.
Are diatomic elements stable when in molecular form?
Yes, these chemical elements are stable.
What are the names of all the man made elements on the periodic table?
Transuranium Elements
