PHYSICS / CHEMISTRY
hi. i'm studing basic wavefunction.
but i don't know the solution of second picture's question.
first picture is main example, and second one is what i want to solve.
please anybody teach me how those answeres are came out..
thx

The radial nodes of the Top? wavefunction Consider an electron in a hydrogen atom with n=2, 1=0, mi=0. Because the radial wavefunction R2,0 (2-p) (see Table 17.1), the radial node is found at p=2. Using eqns 17.8 and 17.9, we find, with Z=1 and n=2, 4360 h P = 23r Me² = 2a 4ILEG? пар r= 2Z a. Me e² Therefore, there is zero probability of finding the electron in a small volume element at a distance 105.8 pm from the nucleus in the hydrogen atom.

For an infinitely heavy nucleus (or one that may be assumed to be), u=m and a=a, the Bohr radius. what i want to know Find the radial nodes for an electron in Li2+ ion with n=3,1=0, m=0. Answer: (331/3)a,/2, 125 and 33.5 pm Why?
