How many of the following statements are false, pertaining to a completely filled p-subshell?

(a) It is spherically symmetric. (b) It has tetrahedral symmetry. (c) It has octahedral symmetry. (d) It is asymmetric. (e) Its symmetry depends on the principal quantum number. (f) It is 3-fold degenerate. (g) For all three orbitals, the value of magnetic quantum number is 1. (h) The value of orbital angular momentum for any electron is .

Answer: 5

Solution

A completely filled subshell consists of , each symmetric about its own axis; together they combine to give overall spherical symmetry — so (a) is TRUE. Hence (b) tetrahedral, (c) octahedral and (d) asymmetric are all FALSE descriptions, and (e) is FALSE since the symmetry depends on , not on
