As element is a unit of matter so how it is possible to prepare some artificial elements its not clear 2 me

The matter making up artificial ('man-made') elements is not "new" matter being created, it is mater which already existed but has just been combined into a new form.
The type of element an atom is depends on the number of protons in the atom's nucleus. All one needs to do to create a new element is add extra protons to the nucleus of already existing atoms, thus transforming it into a new element.
There are plenty of extra protons and other nuclear material available in the universe, so one just needs to "Shoot" it into an atom (not the easiest task in the world, it is very energy intensive in practicality) and get it to combine with the existing nucleus.
Often times, these new elements are very unstable and decay very quickly (sometimes within a few fractions of a second). When the atom decays, the reverse process is happening. Sub atomic particles are coming out of the nucleus of the atom or splitting into smaller nuclei.
In all this process, the number of sub atomic particles remains constant. There can be an ever-so-small change in the "mass" due to the difference in energy contained within the nuclei (due to the strong nuclear force) but this is still conserved according to the law of conservation of energy.
The laws of conservation of mass and conservation of energy are very closely related and can even be combined together due to the relationship between the two (E = mc^2) into the law of conservation of mass-energy.

I think you are young student and learning. Matter can not be created nor destroyed. But it can be converted. Artificial elements are not created in sense of science but they are created in sense of English. As per science this is conversion. For example Hydrogen gets converted to Helium in Sun and we get heat energy. this process is conversion. I hope it clarifies

definition of matter is "anything that occupies space and has mass is called matter"
the line u say is law of conservation of energy
an element consists of atoms which contain nucleus and electrons orbiting nucleus.
nucleus consists of protons and neutrons.
the no. of protons , neutrons and electrons is different in different elements
hence if u can create a nucleus with no. of protons and neutrons different than existing ones u can create artificially some new element

Artificial elements are still composed of pre-existing matter, subatomic particles which existed before the substance was developed.

because you simply make the artificial elements out of other elements
when you are done, you still have the same amount of mass you had at the beginning
