How many known elements are there?

Answer 1

There are 118 elements know to man at this date. That is to say that man has created an atom which contains 118 protons, 118 neutrons, and 118 electrons. This fell apart as soon as it was created, as do most synthetic elements. There are only about 91 naturally occurring and semi-stable elements, the remaining 27 are scientifically lab founded..

Answer 2

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.

Answer 3

There are 118 known elements, with 94 occurring naturally on Earth and the rest being synthesized in laboratories.

Answer 4

The current standard table contains 118 elements of which the transuranic elements were created artificially in a lab but traces of two of them have now been found in nature.

Answer 5

So far, 117 elements are known to exist: the first 118 on the periodic table minus #117.

Answer 6

One-hundred and eighteen. Twenty-seven were scientifically founded, the remaining nighty-one are naturally occurring.
