One electron 'off' to become Ag+ = [Kr] 4d10 5s0
Silver needs 7 more electrons to reach a "pseudo-noble gas" configuration.
One
The pseudo noble-gas electron configuration has the outer three orbitals filled, the s, p and d- s2p6d10 (18 electrons total) and so is fairly stable. Elements that attain this electron configuration are at the right side of the transition metals (d-block). Br-, I-, Se2-
1st electron shell can hold 2 electrons;2nd electron shell can hold 8 electrons;3rd electron shell can hold 18 electrons;4th electron shell can hold 32 electrons.
Cadmium forms ion with +2 charge. It is Cd2+

one electronthe configuration of silver is1s2 2s2 2p6 3s2 3p6 3d10 4s2 4p6 4d10 5s1you take away one electron and the configuration is1s2 2s2 2p6 3s2 3p6 3d10 4s2 4p6 4d101 electron
it all depends on the electron configuration if it is positive or negative, you have to look at the transition metals and valence electrons and determine the charge and use the formula n-11s^2 2s^2 2p^6 3s^2 3p^6 3d^10
Although the formation of an octet is the most stable electron configuration, other electron configurations provide stability. These relatively stable electron arrangements are referred to a pseudo-noble gas configuration.

no. it doesn't

No, that electron configuration does not exist. After the 3p orbital fills with electrons, the next lowest energy orbital is 4s. After 4s contains 2 electrons, then 3d can accept electrons, upto 10. The element with this electron configuration is zinc, one of the transitional metals. Although 3d is full, those electrons can be 'valence' electrons and given to non-metals to form ions, such as Zn+2 or Zn+4. So 3d really acts like a 4th shell orbital and will still be quite reactive even when full. To see just how reactive these electrons are, look at the youtube videos embedded in this site: http://www.chemicool.com/elements/zinc.html.
It will have a pseudo noble gas configuration of [Kr]4d10 after losing the four electrons
