Question

True or false. Please explain your reasoning

In the H-atom ground state, the electron rotates around the nucleus with an angular momentum of h. (This is what Bohr's "old quantum theory" predicted, which is still presented in some textbooks.) Atkins et al. in their textbook have derived the hydrogen-atom orbitals from first principles. We have derived the 1s, 2s, and 2p orbitals from first principles. p_z-orbitals have elongated double-teardrop shapes, with the thin ends of the "drops" connected at the nucleus. A 2s orbital is simply a twice-larger version of a 1s orbital. All atomic orbitals have the maximum electron probability density at the nucleus.

Explanation / Answer

a) in the hydrogen atom ground state, the electron rotates around the nucleus with an angular momentum of h: True

Accordint to Bohr's theory

b) Atkins et al in their textbook have deirved the hydrogen atom orbtials from first principles: True

c) we have derived the 1s 2s and 2p orbtials from first principles: True

d) the shape of pz orbtials : p orbitals have one angular node. htey have elongated double teardrop shapes.

e) No a 2s orbital is not twice larger version of a 1s orbtial

f) False: For s orbital the maximum electron porbability density at the nucleus
