Answer

Explanation:

Step1: Recall ion - formation rules for transition metals

Transition metals can form ions with multiple charges due to the involvement of electrons from the (d) - subshell in addition to the outer - shell (s) electrons.

Step2: Analyze zinc

Zinc ([Ar]3d^{10}4s^{2}) usually forms a (+ 2) ion by losing the two (4s) electrons. It has a full (3d) sub - shell and is less likely to form multiple - charged ions.

Step3: Analyze iron

Iron ([Ar]3d^{6}4s^{2}) can lose the two (4s) electrons to form (Fe^{2 +}), and can also lose one more electron from the (3d) sub - shell to form (Fe^{3+}). So it can form ions with multiple charges.

Step4: Analyze sodium

Sodium ([Ne]3s^{1}) is a main - group metal and usually loses its one (3s) electron to form (Na^{+}). It does not form multiple - charged ions.

Step5: Analyze cobalt

Cobalt ([Ar]3d^{7}4s^{2}) can lose the two (4s) electrons to form (Co^{2+}), and can also lose one more electron from the (3d) sub - shell to form (Co^{3+}). So it can form ions with multiple charges.

Step6: Analyze silver

Silver ([Kr]4d^{10}5s^{1}) usually loses its (5s) electron to form (Ag^{+}), but can also form (Ag^{2+}) in some cases by losing an electron from the (4d) sub - shell. So it can form ions with multiple charges.

Answer:

iron ([Ar]3d^{6}4s^{2}), cobalt ([Ar]3d^{7}4s^{2}), silver ([Kr]4d^{10}5s^{1})
