The heaviest atom known today is 294Uuo, an isotope of ununoctium.
who introduced the first Periodic Table
Metal is located throughout the periodic table. The periodic table is based on atomic weight. Metals range from some of the lightest to the heaviest of elements.
Uub and Uuq are listed on most periodic tables as the heaviest elements. (You can check the number at the bottom of the box, that is its atomic mass or weight
Yes, the heaviest atoms, which have the most protons and electrons, are found towards the bottom of the periodic table in the actinide and transactinide series. These elements have high atomic numbers and are generally unstable and radioactive.
About 2/3 of the Periodic Table of Elements is made up of Metals.
This number you see next to the name on the periodic table is called the atomic number. It is ordered from lightest to heaviest, judging of the weight of an element's specific atom.

At the lower right corner of the Periodic Table.
The heaviest element in the periodic table (known in March 2013) is ununoctium.
Osmium
A atom is not on the periodic table, atoms are inside the elements and compounds on the periodic table if this helps :)
osmium and iridium
The most stable atom in the periodic table is helium.
This element is francium.
The heaviest (hevest?) naturally occurring element is Uranium (238 a.m.u.) but the heaviest known element is atom number 114, 117 or 118, the exact mass being unknown but over 250.
Referring to the Periodic Table, it is Radon (Rn), atomic number 86 (the heaviest being ununoctium)
Metal is located throughout the periodic table. The periodic table is based on atomic weight. Metals range from some of the lightest to the heaviest of elements.
