GENERAL CHEMISTRY CHAPTERS 7 & 8 - ATOMIC STRUCTURE AND PERIODICITY PAGE 16 OF 28 s Orbitals All s orbitals are spherical The probability of finding an s electron depends only on distance from the nucleus, not direction Each principal energy state has 1 s orbital Lowest energy orbital in a principal energy state We have a boundary where we say the electron spends 95% of its time Although s orbital are spherical, there are significant differences among s orbital in different shells The size of the s orbital increases in successively higher shells (electron farther from nucleus) The electron distribution in an outer shell s orbital has more than one region of high probability A 2s orbital = a sphere within a sphere = 2 regions of high probability Each region is separated by a surface of zero probability = node Number of nodes = (n – 1)

GENERAL CHEMISTRY CHAPTERS 7 & 8 - ATOMIC STRUCTURE AND PERIODICITY PAGE 17 OF 28 p Orbitals Each principal energy state above n = 1 has 3 p orbitals Each of the 3 orbitals point along a different axis p x , p y , p z 2 nd lowest energy orbitals in a principal energy state Two-lobed Node at the nucleus, total of n nodes Electron distribution is concentrated in identical lobes on either side of the nucleus and separated by a planar node cutting through the nucleus The probability of finding a p electron near the nucleus is zero d Orbitals The third and higher shells each contain 5 d-
