1s2 2s2 2p6 3s2 3p6 4s2 3d10 4p6 5s1 4d10 that's for silver simplified to Kr 5s1 4d10 The down electron from the 5s moves to fill the d orbitals because it is more stable there a+1 ion (silver's only oxidation state) would be Kr 4d10 Outer orbitals are always removed first, so you cannot start to remove the 4d electrons until all of the 5s are gone.
I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
