Chapter 6.6 representation of orbitals Flashcards
NODES
The number of points at which the probability function goes to zero
Radial probability function
Aka RADIAL PROBABILITY DENSITY
. The probability that we will find the electron at a specific distance from the nucleus
3 trends in radial probability density
. The number of peaks increases with increasing n..the outermost peak being anger than the inner ones
. The number of nodes increases with increasing n( n= 2= 2 nodes)
. The electron density becomes more spread out with increasing n
S ORBITALS
. 1s = the lowest energy orbital of hydrogen atom
. Spherically symmetric and centered from the nucleus
CONTOUR REPRESENTATION
Represents an Orbital shape
. A drawn boundary surface that encloses some substantial portion of the electron density for the orbital
P orbitals
. Electron density is concentrated in 2 regions on either side of the nucleus, separated by a node at the nucleus.
. A dumbbell shape… Which has 2 lobes
. Each set of p orbitals have the same size but differ in orientation
