- Give the ground-state electron configurations and bond orders of(i) F2−, (ii) N2, and (iii) O22−.arrow_forwardThe following observations are made about two hypotheticalelements A and B: The A¬A and B¬B bond lengths in theelemental forms of A and B are 2.36 and 1.94 Å, respectively.A and B react to form the binary compound AB2, which hasa linear structure (that is ∠B-A-B = 180°). Based on thesestatements, predict the separation between the two B nucleiin a molecule of AB2.arrow_forwardConsider the molecular hydrogen dimer, HCl···HCl. Suppose that the bond stretching is described using harmonic potentials, and that the van der Waals interactions between non-bonded atoms are described by Lennard-Jones potential. Write the expression of the interatomic forcefield describing the energy of HCl···HCl.arrow_forward
- Calculate the amount of charge separation for a typical C ¬O single bond, with a bond length of 1.43 Å and a dipole moment of 0.86 D.arrow_forwardWithout consulting tables of data, predict which species has the greater bond length, H2 or He+2.arrow_forwardWhat energy is possessed by .... A. Water held by a dam B. A book in its edge before falling What is the valency of aHydroxyl ion ? If an element X with atomic number of 11 and nitrogen of 7 what is the most likely formula of nitride of X pH2O2——->qH2O+O2. What are the values of p and qarrow_forward
- 1. Neutrons as well as electrons and x-rays can be used to obtain information about molecular structure through diffraction patterns. What must the velocity of a neutron be for its de Broglie wavelength to be about five times smaller than a bond length? How does this velocity compare (bigger, smaller, or the same) if electrons were diffracted? A typical bond length for C-C is 1.54Å (1.54 x 10-1ºm).arrow_forwardThe bond energy of C2 is 599 kJ/mol, the bond distance is 110 pm. Take a rough estimate of the Coulomb repulsion in doubly ionized C2 (i.e., C22+). How far would the C-C bond have to stretch for the Coulomb repulsion to be less than the bond energy in neutral C2? Do you think that the C22+ molecule will still be stable?arrow_forwardIn what ways are the electronic structures of the group 14 (4A) elements similar? In what ways are they different?arrow_forward
- What is the ground state electron configuration for Be+2? What is the bond order for Be+2?arrow_forwardThree biologically Important diatomic species,either because they promote or inhibit life, are (a) CO, (b) NO, and (c) CN−. The first binds to hemoglobin, the second is a chemical messenger, and the third interrupts the respiratory electron transfer chain. Their biochemical action is a reflection of their orbital structure. Deduce their ground-state electron configurations using sigma and pi. (Draw MO). Show how you get electron configuration below using MO?arrow_forwardThe dipole moment of gaseous Ag – Cl is ? = 6.08 D, and the bond distance is r(Ag − Cl) = 228. 1 pm. Calculate the percent ionic character for this bond in the gas phase. In solid form it is however, found the following values for the two silver halides Ag − CL and Ag − F: See image Explain why solid silver chloride is sparingly soluble in water, while solid silver fluoride is moderately soluble B) Explain why solid silver chloride is sparingly soluble in water, while solid silver fluoride is moderately soluble Given extra information: Formal charge: ?? = ??? – (??? + ???); where ??? = valence electrons in free atom, ???= free-pair electrons, ??? = number of bonds to the atom. The elementary charge: ? = 1.6022 × 10−19 C.1 Debye (?)= 3.3356 × 10−30 C × m. The dipole moment has definition: ? = ? × ?, where ? is partialcharge in Coulomb (?), ? is the bond distance (?). Picometer: 1 ?? = 1 × 10−12arrow_forward
