Are there 1000 different elements in the existence?
No. There are 118 currently known elements, of which 98 exist in nature. The other 20 have only been produced in laboratories. Elements beyond that would be too unstable to exist.

How many currently elements?
There are 92 elements that exist in nature*. Every heavier element has decayed before our time. Of course, there are more elements in the periodic table, but they are all synthetic elements-they were made in a laboratory. Theoretically, there is no limit on how heavy an element could become-you can always add a proton to the nucleus. However these synthetic elements exist only for a fraction of a second and only in particle accelerators. There are currently 115 known elements.
What are the three elements in sodium bromide?
