The rules for how many nucleons can be put together in a nucleus are complicated, but basically they predict that as you pack more and more nucleons in past Ni-62, the nucleus gets less and less stable. By the time you reach atomic number 93 and 209 nucleons, there are no more (known) stable isotopes, and it gets harder and harder to synthesize these unstable nuclei.
Theory predicts that there might be a "magic island" of stability, but it's difficult to reach. In particular, it's thought that there might potentially be relatively stable nuclei with atomic numbers 114, 120, and 124. (the most stable isotope of 114 that we know of has a half-life of about 3 seconds, but we haven't managed to pack enough neutrons into it to reach the hypothetical island of stability yet).

∙ 6y agoBeing simplistic: Each atom for that element can be identified by the number of electrons. So it it has one electron, it is hydrogen.

How many element are there in the periodic table?
118
How many boxes are there in the periodic table?
There are 118 elements known and hence there are 118 boxes in the modern periodic table. Each box represent a given element.
How many chemical element do you have in your periodic table?
Today (June 2013) the periodic table contain 118 chemical elements, natural or artificial.
What is the Highest atomic number on the Periodic Table?
The element provisionally named ununoctium, believed discovered in 2003, has atomic number 118 in Period 7, column 18, with an atomic weight of 294. Once confirmed, it will be given its permanent element name.
How many identified elements does the periodic table show?
There are only 117 out of 118 elements on the Periodic Table that have been identified by research groups. Only 112 of the 117 have been recognized by the IUPAC. So, technically, there are 118 elements.
How many elements are there in periodical table?
There are 117 elements in the periodic table. Elements 1-116 and element 118. IMPROVED ANSWER --------------------------------------------------------------------------------------- 118, but element 117 is so unstable they do not officially count it as being an element on the periodic table yet.

118
How many element are in the periodic table?
118 elements
What is element 118 on the periodic table?
Ununoctium. (Uuo)
What element numbers on the periodic table of the elements are man made?
95- 118
How many boxes are there in the periodic table?
There are 118 elements known and hence there are 118 boxes in the modern periodic table. Each box represent a given element.
Which element in the periodic table has an atomic number of 118?
Ununhexium Provisional name for the synthetic element not yet proven to exist
How many chemical element do you have in your periodic table?
Today (June 2013) the periodic table contain 118 chemical elements, natural or artificial.
Have you found all of the possible elements?
The last element for which there are claims of discovery is Uus, element 117. That completes the 118 elements on the periodic table.
What can be found in a periodic table?
The Periodic Table states all known Elements, and element's atomic number, and if a element is metalic or non-metalic.
What element has 19126 protons?
None of them. That's way to many protons for any element. The highest number of protons in the periodic table is only 118.
What is the Highest atomic number on the Periodic Table?
The element provisionally named ununoctium, believed discovered in 2003, has atomic number 118 in Period 7, column 18, with an atomic weight of 294. Once confirmed, it will be given its permanent element name.
