Write the electron configurations of cu2 + and ag+. is each electron configuration consistent with the color you observed for each cation? explain.

(1) Copper:

Copper has the atomic number : 29

Cu2 + means that it lost 2 electrons, therefore, the total number of electrons is 29-2 = 27 electrons.

The electronic configuration is:

1s2 2s2 2p6 3s2 3p6 3d9

(2) Silver:

Silver has atomic number : 47

Ag + means that it lost one electron, therefore, the total number of electrons is 47-1 = 46 electrons

The electronic configuration is:

1s2 2s2 2p6 3s2 3p6 3d10 4s2 4p6 4d10
