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 5f - 6d electrons does not require a large amount of energy and examples of compounds with ππacid ligands are known in which all the 5f, 6d, 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. The following questions are multiple choice questions. Choose the most appropriate answer:

Answer:
The actinoid series is a set of elements that have similar electron configurations and fill the 5f orbitals in order. However, their chemical properties are not uniform, and each element in the series has characteristic properties.
The actinoid series consists of 14 elements, starting from actinium (Ac) to lawrencium (Lr). These elements include uranium (U), plutonium (Pu), americium (Am), and others. However, thorium (Th) does not belong to this series.
1. Electron Promotion: Actinoids can promote their 5f - 6d electrons without requiring a large amount of energy. This means that the 5f, 6d, 7s, and 7p orbitals can all participate in bonding with certain ligands.
2. Oxidation States: Trivalent compounds (with an oxidation state of +3) are the most common in actinoids. However, other oxidation states are also possible. Notably, thorium, protactinium, uranium, and neptunium tend to assume oxidation states of 4 or higher.
3. Chemical Properties: Each element in the actinoid series has its own characteristic chemical properties. This means that their behavior in reactions and their ability to form compounds can vary.
Among the given options, the element that does not belong to the actinoid series is thorium (Th). While thorium has some similarities to actinoids, it is not considered a part of the actinoid series. Thorium belongs to the series of elements known as the "thorium series" or "thorium family."
The actinoid series consists of 14 elements, and thorium does not belong to this series. Although actinoids have similar electron configurations, their chemical properties are not uniform, and each element exhibits characteristic properties.
Introduction
The actinoid series is a set of elements that have similar electron configurations and fill the 5f orbitals in order. However, their chemical properties are not uniform, and each element in the series has characteristic properties.
Explanation
The actinoid series consists of 14 elements, starting from actinium (Ac) to lawrencium (Lr). These elements include uranium (U), plutonium (Pu), americium (Am), and others. However, thorium (Th) does not belong to this series.
Properties of Actinoids
1. Electron Promotion: Actinoids can promote their 5f - 6d electrons without requiring a large amount of energy. This means that the 5f, 6d, 7s, and 7p orbitals can all participate in bonding with certain ligands.
2. Oxidation States: Trivalent compounds (with an oxidation state of +3) are the most common in actinoids. However, other oxidation states are also possible. Notably, thorium, protactinium, uranium, and neptunium tend to assume oxidation states of 4 or higher.
3. Chemical Properties: Each element in the actinoid series has its own characteristic chemical properties. This means that their behavior in reactions and their ability to form compounds can vary.
Thorium is not an Actinoid
Among the given options, the element that does not belong to the actinoid series is thorium (Th). While thorium has some similarities to actinoids, it is not considered a part of the actinoid series. Thorium belongs to the series of elements known as the "thorium series" or "thorium family."
Conclusion
The actinoid series consists of 14 elements, and thorium does not belong to this series. Although actinoids have similar electron configurations, their chemical properties are not uniform, and each element exhibits characteristic properties.
