A certain oxygen atom has the electron configuration 1s22s22px22py2. How many unpaired electrons are present? Is this an excited state for oxygen? In going from this state to the ground state, would energy be released or absorbed?
Answer to relevant QuestionsHow many unpaired electrons are present in each of the following in the ground state: O, O+, O-, Os, Zr, S, F, Ar? The radius trend and the ionization energy trend are exact opposites. Does this make sense? Define electron affinity. Electron affinity values are both exothermic (negative) and endothermic (positive). However, ionization ...Three elements have the electron configurations 1s22s22p63s23p6, 1s22s22p63s2, and 1s22s22p63s23p64s1. The first ionization energies of these elements (not in the same order) are 0.419, 0.735, and 1.527 MJ/ mol. The atomic ...Complete and balance the equations for the following reactions. a. Li(s) + N2(g) → b. Rb(s) + S(s) → c. Cs(s) + H2O(l) → d. Na(s) + Cl2(g) → 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 ...
