Formula for the given question is:
Velocity= frequency X Wavelength.
v= f X λ.
25 = 10 X f
f= 2.5 Hz
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>
5000L • 1 mole /22.4L so approximately 223 moles
