Question

Effective nuclear charge of copper ion

Answer 1

Answer:

cu +2

Explanation:

cu atomic no.29 also its electronic configuration is 3d9 4s2 so during excitation it forms cuprous and cuppric ions(+3)

Answer 2

Answer:

The formula is different for a electrons & d electrons , but the number of protons is the same for the same atom , copper , Z = 29 . You can conclude that the 4s electron experiences a lower effective nuclear charge and is therefore more likely to be lost than the 3d electron ,

should the copper atom becom ionized .
