Newly discovered elements, those odd trans-uranium metals that inhabit the extreme upper end of the Periodic Table, are notproducts of combustion. Combustion is, in general, a chemical process. Only a nuclear process of some kind can create these ultra-heavy elements. We know that the elements up through uranium are created in stars (with the trans-iron elements created in supernovae). The heaviest elements, those that are most recelty discovered, were created by man.
We use some kind of nuclear accelerator (like a cyclotron, for example) to launch particles or heavy nuclei at samples of the heaviest elements. This can result in having those target nuclei capture the particles or heavy ions and change into a yet heavier element. Additionally, continuous bombardment produces heavier still nuclei (along with a good bit of radiation).

Because he knew from his already discovered periods and groups of elements that the gaps would be filled by newly discovered elements. If you have a gap such as this, 3d5__3d7 along a period's outer valance level you can predict, which Mendeleev did, that the element with the outer valance number, 3d6, will be found in the future.
Mendeleev predicted the existence of unnatural elements by leaving gaps in his periodic table for elements that had not yet been discovered. He used the properties of known elements around these gaps to infer the characteristics of the missing elements, thereby predicting their existence. This approach proved successful when later discoveries confirmed the existence of these predicted elements.
Any newly discovered synthetic elements are extremely radioactive and have extremely short half-lives and only a few atoms at most can be produced. At the moment, science is not able to isolate enough for a long enough time. Therefore, it would be difficult to collect and keep enough of the element to determine its chemical and physical properties.
Both Neptune and Pluto were discovered in the early 20th century. Neptunium and Plutonium were later named after these planets by scientists involved in the discovery of these elements, reflecting the trend of naming newly discovered elements after celestial bodies around that time. The names also carry on the tradition of using Roman mythology in naming elements.

The pluralized form of the phrase "newly discovered fish breed" is "newly discovered fish breeds".
Yes they need to be approved by the IUPAC - The International Union of Pure and Applied Chemists. This is for standardisation purposes. Usually elements are named after the place or person who discovered/isolated them.

Cartier named the newly discovered land "Canada" after the Iroquois word "kanata," meaning village or settlement.

Most elements are not named after those who discovered them. Only one element was named after a person who was still alive at the time: Seaborgium was named after Glenn Seaborg, who was credited as a co-discoverer. By this time all newly discovered elements had to be synthesized in particle accelerators and therefore their discovery could not be attributed to any single scientist.
