Question
Explain physical properties of transition elements.
✓
Answer
ty → All the transition elements are metallic element.
→ All the transition metals have high tensile strength, ductility, malleability, high thermal and electrical conductivity and metallic lustre.
→ With the exceptions of Zn. Cd. Hg and Mn, they have one or more typical metallic structures at normal temperatures.
(bcc body centred cubic; hcp = hexagonal close packed;
ccp = cubic close packed; X = a typical metal structure).
→ The transition metals (with the exception of Zn, Cd and Hg) are very much hard and have low volatility.
→ Their melting and boiling points are high.
→ All the transition metals have high tensile strength, ductility, malleability, high thermal and electrical conductivity and metallic lustre.
