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) N2O4 1) There are two N atom = di 2) Name of N = nitrogen 3) There are four O atom = tetra 4) Stem of oxygen is ox , add ide = oxide Name of the compound: DINITROGEN TETRAOXIDE Similary the others will be; (b) Diphosphorus pentaoxide (c) Tetraphosphorus decaoxide (d) Phosphorus hexachloride.. Compounds resulting from the combination of a metal and one or more nonmetals are considered ionic. 2. Compounds resulting from combinations of a nonmetal with other nonmetals are considered molecular.
