Compare metallic properties (density, melting point, hardness, conductivity, magnetic and reactivity notes) for the first-row transition metals Sc (21) through Zn (30).·0 takes
01·Which element in the series Sc–Zn has the highest standard density (room-temperature, solid)?
02·Which element in the series Sc–Zn has the highest melting point?
03·Which element in the series Sc–Zn has the lowest melting point?
04·Which element in the series Sc–Zn is known for the highest electrical conductivity?
05·Which element in the series Sc–Zn is characteristically brittle (not ductile/malleable) in its pure metal form at room temperature?
06·Which element in the series Sc–Zn is diamagnetic in its metallic form due to a filled d10 subshell?
07·Which element in the series Sc–Zn is noted for exceptionally high hardness among them (hard, brittle metal often used for plating and wear resistance)?
08·Which 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?
09·Overall trend in densities across Sc → Cu (21 → 29): do densities generally (increase, decrease, stay constant)?
10·Typical melting-point trend across Sc → Zn: what is the general pattern?
