FAQs on Trends in Physical Properties of Transition Elements Video Lecture - Chemistry Class 12 - NEET

1. What are transition elements?
Ans. Transition elements are a group of chemical elements that have partially filled d orbitals in their atomic or ionic states. They are located in the middle of the periodic table, between the main group elements.
2. What are the physical properties of transition elements?
Ans. Transition elements exhibit several physical properties, including high melting and boiling points, high densities, good electrical and thermal conductivity, and the ability to form colored compounds.
3. How do the physical properties of transition elements vary across the periodic table?
Ans. The physical properties of transition elements vary across the periodic table due to differences in their atomic structures. Factors such as atomic size, electron configuration, and the presence of unpaired electrons in d orbitals affect their physical properties.
4. Why do transition elements have high melting and boiling points?
Ans. Transition elements have high melting and boiling points due to the strong metallic bonding present in their structures. The partially filled d orbitals allow for effective overlap of atomic orbitals, resulting in strong metallic bonding forces.
5. Why do transition elements exhibit good electrical and thermal conductivity?
Ans. Transition elements exhibit good electrical and thermal conductivity due to the presence of delocalized electrons in their structures. These delocalized electrons are free to move and carry electric current or transfer thermal energy efficiently within the metal lattice.
