The first ionization of Li to Li+1 is 520 kj/mole the third ionization Li+2 to Li+3 requires 1.18 x 10^4 kl/mole, and the complete ionization of Li to Li+3 requires 1.96 x 10^4 kj/mole. Using these data, calculate the wavelength of a laser photon resulting in the second ionization of Li, namely Li+1 >Li+2

A Si 13+ ion is originally in the n=9 excited state. How much energy would it take to fully ionize the atom? Give your answer in eV.

An atom is ionized so that it has only one electron. When the electron drops from the n = 3 shell to the n = 1 shell, an X-ray of wavelength 121.97 pm is emitted. What is the atomic number?

Like Het, the Li2+ ion is a single-electron system. Part A Orbital energies in single-electron atoms or ions, such as Het, can be described with an equation similar to the Balmer-Rydberg equation: 1 1 Z°R m2 1 n² where Z is the atomic number.

What is the hybridization and electron geometry of the N, C and interior O in CH3NO2 (lone pairs not shown)

Metallic silver absorbs a small amount of light at the blue (short wavelength) end of the visible light spectrum due to electronic transitions from the atomic 4d to the 5s shells.  How will this affect the color of the reflected light?

The energy of a vibrating molecule is quantized much like the energy of an electron in the hydrogen atom. The energy levels of a vibrating molecule are given by the equation En = (n +1/2)hv  where n is a quantum number with possible values of 1, 2,..., and n is the frequency of vibration. The vibration frequency of HCl is approximately 8.85x10^13 s^-1. What minimum energy is required to excite a vibration in HCl? What wavelength of light is required to excite this vibration?

Question 13 of 29 Neutron diffraction, like X-ray diffraction, is useful in some kinds of structure determinations. What is the de Broglie wavelength of a neutron (mass = 1.009 amu) moving at a velocity of 9.11 × 106 meters per second? 1 4 7 +/- 2 3 LO m 5 6 8 9 O Submit X x 100 +
