Answer

Explanation:

Step1: Understand ion - formation with multiple charges

Elements with partially filled d - orbitals often form ions with multiple charges. This is because electrons from both the outer s - orbital and the d - orbital can be lost during ionization.

Step2: Analyze zinc

Zinc has an electron configuration of [Ar] 3d$^{10}$4s$^{2}$. The d - subshell is completely filled. It usually forms a + 2 ion by losing the two 4s electrons and does not form ions with multiple charges.

Step3: Analyze iron

Iron has an electron configuration of [Ar] 3d$^{6}$4s$^{2}$. It can lose the two 4s electrons to form Fe$^{2 + }$, and can also lose one more electron from the 3d - subshell to form Fe$^{3+}$. So, it can form ions with multiple charges.

Step4: Analyze sodium

Sodium has an electron configuration of [Ne] 3s$^{1}$. It usually loses the single 3s electron to form a Na$^{+}$ ion and does not form ions with multiple charges.

Step5: Analyze cobalt

Cobalt has an electron configuration of [Ar] 3d$^{7}$4s$^{2}$. It can lose the two 4s electrons to form Co$^{2+}$, and can also lose one more electron from the 3d - subshell to form Co$^{3+}$. So, it can form ions with multiple charges.

Step6: Analyze silver

Silver has an electron configuration of [Kr] 4d$^{10}$5s$^{1}$. It usually loses the 5s electron to form Ag$^{+}$, but can also lose electrons from the 4d - subshell in some cases to form ions with other charges. 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}$
