Concept explainers
Interpretation: The ionic Lewis structure for each of the given compound is to be written along with the covalent structure for polyatomic ion. Resonance structure is to be written wherever required.
Concept Introduction: A Lewis structure is used to represent the valence electrons and bonds present in a molecule.
Dots in the Lewis structure represent the valence electrons.
Total number of electrons for Lewis structure can be calculated by summing the valence electrons of each atom in the molecule.
In ionic bonds, transfer of electrons takes place from metal to non-metal.
In covalent bonds, electrons are shared between each of the atom.

- Lewis structures can be used to understand why some molecules react in certain ways. Write the Lewis structures for the reactants and products in the reactions described below. a. Nitrogen dioxide dimerizes to produce dinitrogen tetroxide. b. Boron trihydride accepts a pair of electrons from ammonia, forming BH3NH3. Give a possible explanation for why these two reactions occur.arrow_forwardThink of forming an ionic compound as three steps (this is a simplification, as with all models): (I) removing an electron from the metal; (2) adding an electron to the nonmetal; and (3) allowing the metal cation and nonmetal anion to come together. a. What is the sign of the energy change for each of these three processes? b. In general, what is the sign of the sum of the first two processes? Use examples to support your answer. c.
