- 01Which element in the series Sc–Zn is known for the highest electrical conductivity?
- 02Which element in the series Sc–Zn has the highest standard density (room-temperature, solid)?
- 03Which element in the series Sc–Zn has a filled d-subshell (d10) that leads to relatively low chemical reactivity compared with other first-row transition metals?
- 04Which element in the series Sc–Zn is diamagnetic in its metallic form due to a filled d10 subshell?
- 05Which element in the series Sc–Zn has the lowest melting point?
- 06Typical melting-point trend across Sc → Zn: what is the general pattern?
- 07Which element in the series Sc–Zn is noted for exceptionally high hardness among them (hard, brittle metal often used for plating and wear resistance)?
- 08Which element in the series Sc–Zn is characteristically brittle (not ductile/malleable) in its pure metal form at room temperature?
- 09Which element in the series Sc–Zn has the highest melting point?
- 10Overall trend in densities across Sc → Cu (21 → 29): do densities generally (increase, decrease, stay constant)?
