The probability of finding an electron at a point in an atom is referred to as the probability density (Ï2). The spatial distribution of these densities can be derived from the radial wave function R(r) and angular wave function Y(Î¸,Ï), then solving the SchrÃ¶dinger equation for a specific set of quantum numbers.

Which of the following statements about nodes and probability density are accurate?

	a-The 2s orbital does not have any nodes.
	b-The probability of finding an electron at the center of a p orbital is zero.
	c-The 3p orbitals have two nodes.
	d-The probability of finding an electron at the center of a d orbital is greater than zero.
	e-The 4f orbitals have three nodes.

(a) What are the similarities of and differences between the 1s and 2s orbitals of the hydrogen atom? (b) In what sense does a 2p orbital have directional character? Compare the “directional” characteristics of the p_x and d_x² _- _y² orbitals. (That is, in what direction or region of space is the electron density concentrated?) (c) What can you say about the average distance from the nucleus of an electron in a 2s orbital as compared with a 3s orbital? (d) For the hydrogen atom, list the following orbitals in order of increasing energy (that is, most stable ones first): 4f, 6s, 3d, 1s, 2p.

Consider the discussion of radial probability functions in “A Closer Look” in Section 6.6. (a) What is the difference between the probability density as a function of r and the radial probability function as a function of r? (b) What is the significance of the term 4r² in the radial probability functions for the s orbitals? (c) Based on Figures 6.19 and 6.22, make sketches of what you think the probability density as a function of r and the radial probability function would look like for the 4s orbital of the hydrogen atom.
