Write the expected electron configurations for each of the following atoms: Cl, As, Sr, W, Pb, Na+, I-, Mg 2+, S2-, and Cf.?

I'm certainly not going to do all of them, but here are a few to get you started and hopefully you can do the rest.
Cl (17 electrons): 1s2 2s2 2p6 3s2 3p5
Na+ (Na lost 1 e- so has 10 electrons): 1s2 2s2 2p6 3s1
I- (I gained 1 e- so has 54 electrons): [Kr]5s2 4d10 5p6
