hi All can someone help me , how can I find the energy and the wavelength of the K-alpha x-rays of aluminum ,please ?:frown: I hope someone replys soooon

Hi , I have an other question , I know Its a stupid question to you brialliant ppl :shy: but I hope I find the answer here why are Cl atoms more chemically active than Cl- ion ? and why are Na atoms more chemically active than Na+ ion ? thanx

thank you very much , I really appreciate your help :)
