When silver ionizes, it donates one electron. A neutral Ag atom has 47 electrons. When it ionizes, it becomes 46. The electronic configuration becomes: [Kr]5s¹4d⁹. Thus, the quantum numbers are:

<em>n = 1,2,3,4,5</em>
<em>l = 0,1,2,3,4    ||  (0 to n-1)</em>
<em>ml = -4,-3,-2,-1,0,1,2,3,4    || (-l to +l)</em>
<em>ms = +1, -1  </em>
