FAQs on Variable Oxidation States of Transition Elements Video Lecture - NEET

1. What are transition elements?

Ans. Transition elements are a group of chemical elements that have partially filled d or f orbitals in their atomic or ionic states. They are situated in the middle of the periodic table and include elements like iron, copper, and chromium.

2. How many oxidation states can transition elements have?

Ans. Transition elements exhibit variable oxidation states due to the availability of multiple valence electrons in their d orbitals. They can have several oxidation states, ranging from +1 to +7 in some cases.

3. Why do transition elements show variable oxidation states?

Ans. The variable oxidation states of transition elements arise from the ability of these elements to lose or gain electrons from their d orbitals. The energy difference between different oxidation states is relatively small, allowing for the formation of multiple stable oxidation states.

4. What factors influence the variable oxidation states of transition elements?

Ans. The variable oxidation states of transition elements are influenced by factors such as the electronic configuration of the element, the nature of ligands in a coordination compound, and the overall stability of the compound formed.

5. How are variable oxidation states of transition elements important in chemical reactions?

Ans. The ability of transition elements to exhibit variable oxidation states is crucial in their involvement in various chemical reactions. It allows them to act as catalysts, participate in redox reactions, and form coordination complexes with different ligands, leading to the wide range of applications in fields such as industry, medicine, and catalysis.
