What is the Valency of copper 2?
Solution: When an element does not have a specific valency, its valency is called variable valency. Copper has valency ‘1’ and ‘2’ that is the number of electrons lost or gained is 1 or 2 in different compounds..
Why is copper a electron configuration?
Why are Cu and Cr exceptions electron configuration? Re: Why are Copper and Chromium exceptions? These two elements are exceptions because it is easier for them to remove a 4s electron and bring it to the 3d subshell, which will give them a half filled or completely filled subshell, creating more stability.
What is Cu 2 called?
