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

In chemistry the law of the indestructibility of matter holds true, but the stipulation is through "normal chemical means".
Matter and energy can be interconverted, but it is through what are considered "supernormal" means. (nuclear physics)
It is kind of like saying "People can't walk through walls".
With the right tools (a shaped charge) people can be allowed to walk through walls.

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.

because an artificial element is made out of other elements
there is no new matter involved
just some old matter re-arranged as a different, and artificial element

matter can be made of different elements (atoms). We just reduce them to atoms and then chemically reunite them together to create artificial matter. Also now with avanced chemistry, we are able to analyse the atom better... and play with it's components.... but we can never change it's nature... it take the energy from the center of a star (like the sun) to do this!

Simple. The principal says, "matter and energy can be neither created nor destroyed. They CAN, however, be TRANSFORMED."
So, artificial elements can be "created" through the transformation of other elements.

They are made of two or more smaller elements. The subatomic particles are taken and are joined together, which becomes a new element. It is not creating matter, rather merely combining it.

because atoms are not the smallest unit of matter. taking apart the smaller bits and putting a lot of them together to make bigger atoms is what the synthetic elements are. and btw, matter can be destroyed, thats E=mc^2 is....
