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 space-filling model of the diatomic molecule dinitrogen, N2. Diatomic molecules are molecules composed of only two atoms, of the same or different chemical elements. The prefix di- is of Greek origin, meaning two. If a diatomic molecule consists of two atoms of the same element, such as hydrogen (H2) or oxygen (O2), then it is said to be homonuclear. Otherwise, if a diatomic molecule consists of two different atoms, such as carbon monoxide (CO) or nitric oxide (NO), the molecule is said to be heteronuclear.
