Question

Quantum Theory and the Electronic structure of atoms;

1-the electron configuration of a neutral atom is 1s²2s²2p^63s². Write a complete set of quantum numbers for each of the electrons. name the element.

2-what is the maximum number of electrons in an atom that can have the following quantum numbers? Specify the orbitals in which the electrons would be found. (A) n=2, ms= +1/2; (b) n=4, mℓ=+1; (c) n=3, ℓ=2; (d) n=2, ℓ=0, ms= -1/2; (e) n=4, ℓ=3, mℓ=-2.

3- certain sunglasses have small crystals of silver chloride (AgCl) incorporated in the lenses. when the lenses are exposed to light of the appropriate wavelengh, the following reaction occurs:

AgCl -------> Ag + Cl

The Ag atoms formed produce a uniform gray color that reduces the glare. If ΔH for the preceding reaction is 248 kJ/mol, calculate the maximum wavelength of light that can induce this process.
