Group 18 as they have completely filled electronic configurations, are stable and hence do not ionize.
Elements with the highest atomic mass can be found towards the bottom of the periodic table, typically in the bottom rows known as the actinide and lanthanide series. These elements include heavy elements such as uranium, thorium, and plutonium.
It is named The PERIODIC TABLE. The periods being the horizontal rows The groups being the vertical columns.
The element with the largest ionization energy in its period is typically found in the top right corner of the periodic table. This is because elements in this region have the highest effective nuclear charge, making it harder to remove an electron. In general, elements like helium, neon, and fluorine tend to have the highest ionization energies in their respective periods.
The elements in the lower right part of the Periodic Table. Cs, Fr, Ra, Ba etc.
118 elements are in the periodic table of elements; some of them are still unnamed (January 2013).
Halogens
The noble gases such as helium, neon, argon, and xenon typically have the highest ionization energies on the periodic table. This is because they have a full valence shell of electrons which makes it difficult to remove an electron.

A period on the periodic table is a row.This is the horizontal section of the periodic table.

Osmium and iridium are the two elements with highest density.
The elements in the lower right part of the Periodic Table. Cs, Fr, Ra, Ba etc.
It is called the Periodic Table of Elements.
Elements to the left of the periodic table are called metals. These elements generally have low ionization energies and tend to lose electrons to form cations. They are good conductors of heat and electricity.
Elements of the Periodic Table
Yes, there were elements on the first periodic table. I believe that there are still elements on the periodic table.
