The radial probability function for a 2s orbital is shown here.

Classify the following statements as either true or false: 

(a) There are two maxima in this function because one electron spends most of its time at an approximate distance of 0.5 Å from the nucleus and the other electron spends most of its time at an approximate distance of 3 Å from the nucleus. 

(b) The radial probability function shown here and the probability density  [Ψ(r)]² both go to zero at the same distance from the nucleus, approximately 1 Å. 

(c) For an s orbital, the number of radial nodes is equal to the principal quantum number, n.
