Examples are: iron, aluminium, tin, zinc, silicon, uranium, manganese, magnesium, chlorine, sulfur, etc.
They are called artificial chemical 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.
'Little Boy' - Uranium whereas 'Fat Man' used Plutonium triggering devices .
Not all the elements occur naturally; some elements are man-made.
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.
All actinides are radioactive elements and some are man made.
All actinides are radioactive elements and some are man made.
Some common types of conflict in narratives include man vs. man, man vs. nature, man vs. self, and man vs. society. These conflicts help drive the plot forward and allow characters to undergo personal growth or change.
They tried to emulate some of the elements of the West while purposely neglecting others.
Man-made elements are used in a variety of ways, such as in manufacturing, technology, research, and medical applications. They can be used in construction materials, electronic devices, pharmaceuticals, and nuclear reactors, among other things. These elements are often synthetically produced to serve specific purposes or address certain needs that natural elements may not be able to fulfill.

some elements in the bottom of the periodic table man has not encountered yet, some are just theories or found on over planets or in space
