प्रश्न
Account for the following:
Transition metals form alloys.
Explain why do transition metals form alloys among themselves.

उत्तर १
Transition metals have very similar atomic sizes as a result one metal can easily replace the other metal from its lattice to form solid solution (alloy). Transition metals are also miscible with one another in the molten state. Thus, the molten state solution of two or more transition metals on cooling forms an alloy.
उत्तर २
- Transition metals have very similar atomic sizes.
- Because of this similarity, one metal atom can easily replace another in the metal lattice.
- This forms a solid solution called an alloy.
- Transition metals are also miscible in their molten state, meaning they mix well when melted.
- Upon cooling, the molten mixture solidifies as an alloy.
- These alloys are usually hard and have high melting points.
Thus, the similar atomic size and good miscibility in the molten state lead transition metals to form alloys easily.
