Question

Which form of silver is colourless?

Answer 1

Silver:

• Silver is found in the $\mathrm{d}$ block of the periodic table, in the eleventh period.
• It is the metal with the greatest electrical conductivity, thermal conductivity, and reflectance.
• It's a silky white metal.

Colourless silver:

• Silver's electrical arrangement is $\left[\mathrm{Ar}\right]4{\mathrm{d}}^{10}5{\mathrm{s}}^1$ using the laws of electrical configuration.
• Because half-filled or fully-filled orbitals are more stable than any other arrangement, the s orbital is not filled and the $\mathrm{d}$ orbital is filled.
• To be colourless, no unpaired electrons should be present.
• ${\mathrm{Ag}}^{+}=\left[\mathrm{Ar}\right]5{\mathrm{d}}^{10}4{\mathrm{s}}^0$
• Therefore, ${\mathrm{Ag}}^{+}$is the form of colourless silver.
