Document Summary

For example: 2s and 2p orbitals are subshells in the 2nd principal quantum level: subshells have the same energy and they are degenerate orbitals. The volume represents 90& probability of finding electron in that orbital. Highest electron density is around the nucleus. A node (0% probability) is present in s and two nodes for 3s orbital. 2s orbital is larger than 1s orbital: the p orbital. There are 3 degenerate p orbitals: px, py, pz along the x, y, and z axes (m . = -1,0,+1) p orbitals posses two lobes; on e on each side of the nucleus. The wave function is the same but with opposite sign in the two lobes. An electron in a p orbital would have equal probability of being found in either lob although it has a zero probability to be found in the nodal plane.
