Stinky Sally was sitting all by her lonesome one day and thought about something silly. "How can I use exactly four 4's and the operations +, -, *, and / to make equations that equal 0, 1, 2, 3, 4, 5, 6, 7, 8, and 9. Then she painted her nails green and colored her hair bright red.

I need help understanding electron configurations and electron configuration tables. The electron configuration for tin(Sn) is:
Sn: 1s2 2s2 2p6 3s2 3p6 3d10 4s2 4p6 4d10 5s2 5p2

(The number after the letter is the number of electrons if you didn't know)
I am confused because the E.C. table has sublevel f. why did the configuration go from 4d10 to 5s2? It skipped the f sublevel. Why is that?
THanx 4 ur help!

(4x^2 a)^2 / 12x^3 a^4. The examples in the book are easy, but I can't find the answer to this one. The question is what is the simplest form?

Also I can't get this one-- (3a^2/b)^2 X b^3/6. What is the product?
I get answers, but none of them match with the choices.
