The one hundred sixth element in the periodic table is Seaborgium, which is a synthetic element with the atomic symbol Sg and atomic number 106. It was first synthesized in 1974 and is named after American physicist Glenn T. Seaborg.
The Periodic table is a table with more than a hundred Elements on it. As of 2010, there are 118. Along with the names of the Elements there is the chemical symbol of the Element, the atomic number, and usually the atomic mass of the Element. The atomic number represents the number of Protons in one atom, and the atomic mass is the mass of the Protons and neutrons added together. The Electrons are not added onto the mass of the Protons and Neutrons because the Electrons are negligible.
I know that there are over a hundred but you can't always say because when more elements are discovered they are put on the periodic table on the standard table there are 118,
The periodic table may change over time as new elements are discovered or as our understanding of atomic structure evolves. New elements can be added to the table, and their properties may lead to a reorganization of the elements. The overall layout and concepts of the periodic table are likely to remain consistent, but the specific details can change.
The 102nd element is called Nobelium (No).
Mendelevium (Md).
There is no permanent name for the 113th element, but its temporary name is Ununtrium (Uut).
To be frank, there is no 114th element and the element Ununquadium as posted before doesn't even exist.

The one hundred seventeenth element in the periodic table is tennessine (Ts). It is a synthetic element with the symbol Ts and atomic number 117. Tennessine is a highly unstable element that was first synthesized in 2010.
The one hundred sixth element in the periodic table is Seaborgium, which is a synthetic element with the atomic symbol Sg and atomic number 106. It was first synthesized in 1974 and is named after American physicist Glenn T. Seaborg.
The one hundred fifteenth element in the periodic table is moscovium (Mc). It is a synthetic element with the atomic number 115 and does not occur naturally on Earth. Its discovery was confirmed in 2010 by a team of Russian and American scientists.
That stands for "One hundred eight Elements in the Periodic Table", but this is now obsolete. As of 2008, at least 117 elements have been discovered.
The 109th element in the periodic table is Meitnerium (Mt). It is a synthetic element and is radioactive, with a very short half-life. It was first synthesized in 1982 by a team of German researchers.
