Given that Z_eff(2s) in Li is 1.26, estimate the energy of the 2s electron in Li in Rhydberg units.

Question

Quizplus · Accepted Answer

The energy of an electron in a hydrogen-like atom is given by the equation:E = -Z^2 * (1/n^2) * R_Hwhere:E is the energy of the electron in Rydberg unitsZ is the atomic number of the atomn is the principal quantum number of the electronR_H is the Rydberg constant (109,737.31 cm^-1)In this case, we are given that Z_eff(2s) in Li is 1.26. This means that the effective nuclear charge experienced by the 2s electron in Li is 1.26. We can use this to calculate the energy of the 2s electron in Li:E = -Z^2 * (1/n^2) * R_HE = -1.26^2 * (1/2^2) * R_HE = -0.40 R_HTherefore, the energy of the 2s electron in Li is -0.40 Rydberg units.
