Sorry, yea, that's what i meant, thx

Oh ok, that's what i didn't understand in quantum numbers, l of 2 indicates a d orbital, but as has no electrons in a d orbital in ground state. thx

11. Which one of the following sets of quantum numbers (n, l, ml, ms) could not possibly describe one electron of an arsenic atom (Z = 33) in its ground state? (A) 2, 1, -1, 1/2 (B) 4, 2, 2, -1/2 (C) 3, 0, 0, -1/2 (D) 3, 2, -2, 1/2 (E) 4, 1, 0, 1/2 Solution: Electron configuration...

sorry i was unclear, basically i was trying to differenetiate the function to find the slope using the old method described by fermat in the 1600's. Anyway, I ended up getting it, thx.

Homework Statement I'm supposed to differentiate a function: (x^3) + 2x Using the standard way used today, and then find the equation of the line so that it passes through (1,3). So I did: 3(x^2) + 2 and then the final equation is y = 5x - 2 right? Then I'm also supposed to differentiate and...

nvm, i figured it out

that doesn't really help me. Maybe mentioning which ones I should use would help, because I start to use some but they don't seem to get me where I want. It's like math class all over again with that darn unit with rearranging cos(x), sin(x), and tan(x), i hated that too.

The question is exactly this: Prove that the maximum speed (Vmax) of a mass on a a spring is given by 2(pi)fA. where f = frequency and A =Amplitude We are given such formulas as: f=[1 / 2(pi)]square_root (k /m) or f=[1 / 2(pi)]square_root (a /-x) the formula for total energy in a...
