1. The s orbital is non directional because
a the probability density function is zero at the nucleus.
b the angular component of an s orbital varies with the principal quantum number (n).
c at a particular distance from the nucleus, the electron probability is the same in all directions.
d the angular distribution of an s orbital depends on the value of ell.
e the electron can be found anywhere within a spherical space surrounding the nucleus.
f an s orbital has angular nodes.
g the wave equation of an s orbital has a constant angular function.
2. The 2p orbital is not spherically symmetric because
a the angular part of the 2p orbital depends on values of theta and phi.
b there are angular nodes in the yz, xz, and xy planes.
c the 2p orbital has radial nodes at finite values of r.
d the 2p orbital does not vanish at r = 0.
e the angular part of the 2p orbital is a constant.
f the value of psi^2 is zero at the nucleus.
