After lead, all elements on the periodic table have only radioactive isotopes.
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.
Group 3 of the periodic table contains many of the radioactive elements.
A periodic chemistry is a periodic table. A periodic table is a tab,e with atoms and elements. Whatever we eat or use have atoms or elements.
Th is element number 90 on the periodic table It is thorium, it is in the Actinides, and it is radioactive
In the left corner down of the periodic table.

Some are, some are not.
A atom is not on the periodic table, atoms are inside the elements and compounds on the periodic table if this helps :)

Radioactive elements exist in all groups of the periodic table.
Periodic table is an arrangement of elements where the elements are arranged in the increasing order of their atomic number. The atoms on the periodic table are not held by any force.
