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.
SI is Sulphur and Iodine, Si is Silicon. Tehy are both different elements on the peridoic table
Group 3 of the periodic table contains many of the radioactive elements.
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.
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.
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.
The periodic table serves as an organizer for the elements. Not only does it group them by the amount of valence electrons they have (the vertical rows,) but it also groups them by having similar properties.
