molecular
Nitrogen oxides are not ionic compounds.
NOCl is a molecular compound because it is composed of nonmetals (nitrogen, oxygen, and chlorine) and forms covalent bonds.
Molecular
PtO2 is ionic
CO is a molecular compound. It consists of a covalent bond between carbon and oxygen atoms.
Nitrogen trifluoride is a molecular compound, not ionic. It consists of covalent bonds between the nitrogen and fluorine atoms.
Nitrogen oxide is a molecular compound, not an ionic compound. It is composed of nitrogen and oxygen atoms bonded together covalently.
Nitrogen dioxide.
Nitrogen oxides are not ionic compounds.
molecular
The molecular formula of sulfur dioxide (SO2) is molecular, not ionic. This compound is made up of covalent bonds between sulfur and oxygen atoms, where they share electrons to form the molecule.
NO is a molecular compound, not an ionic compound. It is made up of individual atoms of nitrogen and oxygen that are covalently bonded together.
K3N is an ionic compound. It is composed of a metal (potassium) and a nonmetal (nitrogen), so it forms an ionic bond due to the transfer of electrons from potassium to nitrogen.
Sodium iodide has ionic bonds, which are always polar. Carbon dioxide and hydrogen gas both have molecular (covalent) bonds; the ones in carbon dioxide are polar and those in elemental hydrogen molecules (H2) are nonpolar.
HNO2 is a molecular compound. It consists of covalent bonds between the nitrogen, hydrogen, and oxygen atoms, rather than ionic bonds typically found in ionic compounds.
NL3, which represents the compound nitrogen trilithide, is an ionic compound. It contains the nitrogen ion with a -3 charge and the lithium ion with a +1 charge.
N2O4 is a molecular compound. It consists of covalent bonds formed between nitrogen and oxygen atoms.
