7.21 Theoretical models for the structure of atomic nuclei predict the existence of superheavy elements that have not yet been discovered and suggest that such elements might be fairly stable if they could be produced. So researchers are currently trying to synthesize these superheavy elements to test these theories. Element 117 has been synthesized and named Tennessine (Ts). What would the Lewis dot symbol be for this new element?
23Na,88Sr2+,Se,Br-,35CI. Which of the following are ions ? Provide reason
(a) The ionization energy of potassium (K) is 4.34 eV and the electron affinity of chlorine (Cl) is -3.61 eV. The Madelung constant for the KCl structure is 1.748 and the distance between ions of opposite sign is 0.314 nm. On the basis of these data only, compute the cohesive energy of KCl per ion pair. (b) The observed cohesive energy of KCl is 6.42 eV per ion pair. On theassumption that the difference between this figure and that obtained in (a) is due to the exclusion principle repulsion, find the exponent n in the formula Br^-n for the potential energy arising from this source.
Two lasers generate radiation of (1) 9.5 µm and (2) 0.1 µm respectively.(a) For each of the radiations, determine the photon energy (in eV).(b) Will either of the two radiations be able to break (dissociate) the Si–H bondin SiH4? Given: ESi-Si = 180 kJ/moleEH-H = 435 kJ/mole
Briefly explain the following observation. S can have an expanded octet and thus SF6 exists(~$1.00 per gram), but O cannot have an expanded octet and thus OF6 does not exist as a stablecompound.
magnesium is it stable or reactive? why? if it reacts with another atom, would it be more likely to accept or to donate one or more electron?
To ionize Mg to Mg2+ costs two times as much energy as to form Mg+. The formation of O2- is endothermic rather than exothermic as for O-. Nevertheless, magnesium oxide is always formulated as Mg2+ O2- rather than Mg+O-a) Give theoretical reason for formulation of Mg2+O2-b) What simple experiment could be done to predict that magnesium oxide wasnot Mg+O- ?
