All elements from atomic number 84 (Polonium - Po) and onwards are radioactive, although ones that have not been observed cannot be confirmed.
It's a table listing the elements, organized in columns of similar types of elements with respect to their chemical bonding characteristics, based on their atomic numbers and electron configurations.
Radioactive elements exist in all groups of the periodic table.
Radioactive elements exist in all groups of the periodic table.
Group 3 of the periodic table contains many of the radioactive elements.
SI is Sulphur and Iodine, Si is Silicon. Tehy are both different elements on the peridoic table
Some examples of radioactive elements on the periodic table include uranium, thorium, radium, and plutonium. These elements have unstable atomic nuclei that decay over time, emitting radiation in the process.
Dmitri Mendeleev is known as the father of the periodic table of elements. He arranged the elements in order of increasing atomic weight and grouped them based on similar properties. Mendeleev's periodic table laid the foundation for the modern periodic table we use today.
all elements after uranium (atomic number 92) are radioactive.
Au stands for gold on the periodic table of elements. It is a precious metal with the atomic number 79.
All elements comprising the period 7 in the periodic table are radioactive. In total this period has 32 elements.

Radioactive substances are not exclusive to the last period of elements on the periodic table, but many of the heaviest elements, particularly those in the actinide and transactinide series, are radioactive. These elements, found at the bottom of the periodic table, typically have unstable nuclei that decay over time. However, there are also radioactive isotopes of lighter elements scattered throughout the periodic table. Thus, while many radioactive elements are at the bottom, not all radioactive substances belong to this category.
