In the second row of the periodic table, Be, N, and Ne all have endothermic (unfavorable) electron affinities, whereas the other second- row elements have exothermic (favorable) electron affinities. Rationalize why Be, N, and Ne have unfavorable electron affinities.
Answer to relevant QuestionsThe electron affinities of the elements from aluminum to chlorine are 244 kJ/ mol, 2120 kJ/ mol, 274 kJ/ mol, 2200.4 kJ/ mol, and 2348.7 kJ/ mol, respectively. Rationalize the trend in these values. The bright yellow light emitted by a sodium vapor lamp consists of two emission lines at 589.0 nm and 589.6 nm. What are the frequency and the energy of a photon of light at each of these wavelengths? What are the energies ...Photogray lenses incorporate small amounts of silver chloride in the glass of the lens. When light hits the AgCl particles, the following reaction occurs: The silver metal formed causes the lenses to darken. The enthalpy ...An alternative definition of electronegativity is Electronegativity 5 constant (I. E. 2 E. A.) where I. E. is the ionization energy and E.
