3 I think I did this a year or too ago and now to get to 20.  \(x^{2} \lim_{n \to \infty} a_n \geq x_{123} \\ \lim_{n \to \infty} a_n \sqrt[n]{x}\) and that is how if u don't understand ill re tell you. ;D

3... because argon has 18 protons and 18 electrons.There are 2 electrons on the first energy level, 8 electrons on the second level, and 8 electrons on the third energy level.
