Question

Explain why transition elements form alloys.

Answer 1

1. Similar atomic sizes, one metal easily replaces another in the crystal lattice to form a solid solution (alloy).
2. Strong metallic bonding from unpaired d‑electrons makes metal-metal bonding favourable, so atoms mix well.
3. Variable valence and similar chemistry let transition metals combine without breaking overall bonding.
4. Interstitial atoms (e.g., C in Fe) and molten‑state miscibility produce hard, high‑melting alloys.
