The actinides line the bottom row of the island and comprise elements 89, actinium.
46+ Actinides On The Periodic Table. The actinides are the row of elements on the periodic table that start with actinium, and include uranium and go up to element 103. Extended periodic tables will show it physically in the 7th row, but it's too impractical to be used normally as the actinides are a long group of 14 elements.

The group 18 elements, on the far right side of the table, for example, have completely full outer shells and actinides: Periodic table actinides illustrations & vectors. In presentations of the periodic table, the lanthanides and the actinides are customarily shown as two additional rows below the main body of the table,2 with placeholders the figure buildup of actinoids is a table of nuclides with the number of neutrons on the horizontal axis (isotopes) and the number of.
The group 18 elements, on the far right side of the table, for example, have completely full outer shells and actinides:
The atomic number of curium is 96 and has the symbol cm. This short review details some of the chemistry that has been reported over the last 15 years, and its consequences for understanding the periodic table. These elements, usually considered ranging from atomic number 89 to atomic number 103 on the periodic table, have interesting properties, and play a key role in nuclear chemistry. At the bottom of the periodic table is a special group of metallic radioactive elements called actinides or actinoids.
