1
Which are differences between s-block metals and d-block metals?
d-block metals form more than one type of cations.
s-block metals have high melting points.
d-block metals are malleable and ductile.
s-block metals can only form 1 type of cation.
2
Which of these transition metals are attracted by an external magnetic field strongly (ferromagnetic)?
silver
iron
cobalt
nickel
3
Why is zinc not classified as a transition element?
Zn atoms contain a full d subshell
zinc does not form complex ions
there are no zinc ions with an incomplete d subshell
zinc ions are colourless
