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.
Polyatomic ions are ions which consist of more than one atom. For example, nitrate ion, NO3-, contains one nitrogen atom and three oxygen atoms. The atoms in a polyatomic ion are usually covalently bonded to one another, and therefore stay together as a single, charged unit. Rule 1.The cation is written first in the name; the anion is written second in the name.or example, nitrate ion, NO3-, contains one nitrogen atom and three oxygen atoms. The atoms in a polyatomic ion are usually covalently bonded to one another, and therefore stay together as a single, charged unit.
