Read the passage given below and answer the following questions: Although actinoids are similar to lanthanoids in that their electrons fill the 5f orbitals in order, their chemical properties are not uniform and each element has characteristic properties. Promotion of 5 - 6d electrons does not require a large amount of energy and examples of compounds with 77 acid ligands are known in which all the 5f, 60, 7s, and 7p orbitals participate in bonding. Trivalent compounds are the most common, but other oxidation states are not uncommon. Especially, thorium, protactinium, uranium, and neptunium tend to assume the +4 or higher oxidation state.
