In CO2, O is more electronegative meaning that it seeks to pull the electron between itself and carbon more strongly which results in unequal sharing of electrons. In O3, when atoms are bonded together, the electrons are shared equally. 7. Analyze whether dinitrogen tetroxide, N2O4, has covalent or ionic bonds.nswers: 1. Determine if the following compounds are likely to have ionic or covalent bonds. a. magnesium oxide, MgO ionic (metal and nonmetal) b. Strontium chloride, SrCl2 ionic (metal and nonmetal) c.
A coordinate covalent bond is a bond formed when both electrons in a bond are donated by one atom. A coordinate covalent bond is not essentially different from other covalent bonds; it involves. the sharing of a pair of electrons between two atoms.attice energy (lattice enthalpy) is the change in energy that occurs when an ionic solid is separated into isolated ions in the gas phase. In general, strength of ionic bonds and lattice energy are directly proportional. A large value in the lattice energy indicates a. strong ionic bond and vice versa.
