Why does silver exhibit a valency of +1 and +2?
An atom of an element can sometimes lose more electrons than are present in its valence shell i.e. loss from the penultimate shell and hence exhibit more than 1 or variable valency. – At other times, silver loses one electron from 5s & 4d each to show valency +2.
Why does silver exhibit variable valency?
Some elements show variable valency because of the different electronic configurations. silver can sometimes lose more electrons than are present in its valence shell i.e. loss from the penultimate shell and hence exhibit more than 1 or variable valency.
Does silver Show +2 oxidation state?
Although its empirical formula, AgO, suggests that the compound tetrasilver tetraoxide has silver in the +2 oxidation state, each unit has two monovalent silver atoms bonded to an oxygen atom, and two trivalent silver atoms bonded to three oxygen atoms, and it is in fact diamagnetic.
Does silver show variable valency?
Silver (Ag) = Argentous (Ag+1) and argentic (Ag+2.) The element that exhibits lower valency will be suffixed with “ous”….Elements with Variable Valency.
| Element | Electronic Configuration | Valency |
|---|---|---|
| Fe (Iron) | 3d6 4s2 | 2, 3, 4, 5, 6, and 7 |
What’s the valency of silver?
+ 1
Generally the valency of silver is + 1 , as the d sub – shell has stable configuration if they lose 1 electron from s sub – shell . therefore the most common valency of silver is 1 .
How do you find the valency of silver?
Generally the valency of silver is + 1 , as the d sub – shell has stable configuration if they lose 1 electron from s sub – shell . therefore the most common valency of silver is 1 .

What is the symbol and valency of silver?
Therefore, the symbol of silver is Ag and the most common valency of silver metal is 1 and 3 .
What is the valency of silver?
There fore the most common valency of silver is 1. But in some exceptional cases it exhibit valency as 2, when it loses electrons from the stable d sub-shell to exhibit transition property of metals. Originally Answered: What is valence of silver?
What elements have a valence of +1 and +3?
All the stable elements of Group IB (Cu, Ag, Au) have a valence of +1. Cu can also have +2, and Au can have +3. Ag was thought to have a valence +2, BUT this was later found out to be a mixture of +1 and +3.
Why do some elements show variable valency?
Some elements show variable valency because of the different electronic configurations. An atom of an element can sometimes lose more electrons than are present in its valence shell i.e. loss from the penultimate shell and hence exhibit more than 1 or variable valency.
What is the electron configuration of silver?
– Silver has electronic configuration [Kr] 4d^10 5s^1. – Being a d-block element, it has ability to show variable oxidation states. – Usually silver loses one electron from 5s to exhibit valency +1. – At other times, silver loses one electron from 5s & 4d each to show valency +2.
