A color-coded periodic table of the elements displays each element's symbol and atomic number, with categories such as alkali metals, noble gases, halogens, transition metals, and actinoid elements distinguished by different background colors. — actinoid element Modern version of the periodic table of the elements (printable).

The actinoid elements that commonly form ions with a +3 oxidation state include actinium and the elements from uranium through einsteinium.1

While thorium and protactinium can exhibit a +3 state, it is considered unstable for these two elements. The chemistry of the actinoids in the +3 oxidation state is characterized by significant similarities, often resembling the lanthanoids of the same state, with their physical properties and crystal structures largely dependent on the size of the +3 ion.1
