Document Summary

Position of electrons (e-) has an uncertainty of (according to. Position of e- are thought to be in regions of probability density, can use schr dinger equation ( Each atomic orbital is described by three quantum numbers. = n, l, ml: quantum numbers only have certain, discrete values, principle quantum number (n) = energy of an e- in the atomic orbital that corresponds to the orbital size. As n increases, the maximum probability density moves farther from the nucleus, increasing the energy of the e: angular momentum quantum number (l) = shape of the atomic orbital. Energy of e- increases as value of l increases due to effects of penetration and shielding. As l increases, ability of an e- in the orbital to penetrate the inner shell e- decreases, Quantum number n (principle) l (angular momentum) ml (magnetic) raising the energy of the e- 0, 1, 2, 3, n-1 s, p, d, f, .
