Consider an electron within the ls orbital of a hydrogen atom. The normalized probability of finding the electron within a sphere of a radius R centered at the nucleus is given by normalized probability = [az-e * (až + 2a, R+ 2R)] where a, is the Bohr radius. For a hydrogen atom, ao = 0.529 Å. What is the probability of finding an electron within one Bohr radius of the nucleus? normalized probability: 0.323 Why is the probability of finding...

2. The hydrogen atom [8 marks] The time-independent Schrödinger equation for the hydrogen atom in the spherical coordinate representation is where ao-top- 0.5298 10-10rn is the Bohr radius, and μ is the electon-proton reduced mass. Here, the square of the angular momentum operator L2 in the spherical coordinate representation is given by: 2 (2.2) sin θー sin θ 00 The form of the Schrödinger equation means that all energy eigenstates separate into radial and angular motion, and we can write...

A hydrogen atom is at the earth’s surface. The electron and
proton in the atom are separated by a distance of 5.29×10?11m. What
is the ratio of the magnitude of the electric force exerted by the
proton on the electron to the weight of the electron?

A hydrogen atom consists of a proton, effectively a point charge of +1.6 × 10^-19C, surrounded by a spherical “electron cloud” of radius 5.3 × 10^-11m and charge −1.6 × 10^-19C. Use Gauss’s Law to find the electric field at a point (a) 2 × 10^-11m from the proton (inside the atom) and (b) 1 × 10^-10m from the proton (outside).

Assuming that the average distance between the electron and the proton in a hydrogen atom is 1.0 angstrom, what is the average force exerted by the proton on the electron?

Problem 10 (Problem 2.24 in textbook) The wavefunction for the electron in a hydrogen atom in its ground state (the 1s state for which n 0, l-0, and m-0) is spherically symmetric as shown in Fig. 2.14. For this state the wavefunction is real and is given by exp-r/ao h2Eo 5.29 x 10-11 m. This quantity is the radius of the first Bohr orbit for hydrogen (see next chapter). Because of the spherical symmetry of ịpo, dV in Eq. (2.56)...

df- Adobe Reader 43.12 Consider the tollowing problem (Stewart 2006). The hydrogen atom con- sists of one proton in the nucleus and one electron, which moves about the nucleus. The electron does not move in a well-defined orbit, but there is a probability for finding the electron at a certain distance from the nucleus. The PDF is given by p(r)-47 exp(-2 r/ao) /a03 for r2 0, where a,- 5.59 x 101 m is the Bohr radius. The integral over this...
