Question

Which is More Ionic \[MnO\] or \[M{{n}_{2}}{{O}_{7}}\]?

Answer 1

Hint: In other words, ionic compounds are ionic compounds that are held together by ionic bonds. Elements can gain or lose electrons to achieve their closest noble gas configuration. The formation of ions for the completion of the octet (either by gaining or losing electrons) aids in their stability.

Complete answer:
The relative sizes of the cations and anions determine the structure of an ionic compound. Salts, oxides, hydroxides, sulfides, and the vast majority of inorganic compounds are ionic compounds. Electrostatic attraction between positive and negative ions holds ionic solids together.
\[MnO\]: Manganese (II) oxide, also known as \[MnO\], is an inorganic compound. It crystallizes into green crystals. The compound is widely used as a component of fertilizers and food additives. \[MnO\], like many other monoxides, has a rock salt structure with octahedrally coordinated cations and anions. Manganese (II) oxide, like many oxides, is frequently nonstoichiometric: its composition can vary from \[MnO\] to \[MnO\]
\[M{{n}_{2}}{{O}_{7}}\]: Manganese (VII) oxide, also known as manganese heptoxide, is an inorganic compound with the formula \[M{{n}_{2}}{{O}_{7}}\]. This flammable liquid is extremely reactive. It is a dangerous oxidizer that was discovered in 1860. It is permanganic acid's acid anhydride. This chemical compound's crystalline form is dark green. Reflected light turns the liquid green, while transmitted light turns it red. It dissolves in carbon tetrachloride and decomposes when exposed to water.
\[MnO\] is more ionic than \[M{{n}_{2}}{{O}_{7}}\] in most cases. Because it has a lower magnitude positive charge, it is more ionic. Furthermore, the electronegativity difference between the two atoms is large \[MnO\], so the bond will have a more ionic character.
Thus, \[MnO\] is more ionic than\[M{{n}_{2}}{{O}_{7}}\].

Note:
Ionic compounds are hard and brittle, with high melting and boiling points. They are almost always electrically insulating as solids, but when melted or dissolved, the ions become mobilized and they become highly conductive. Ionic compounds can also be synthesized from their constituent ions through solvent evaporation, precipitation, freezing, a solid-state reaction, or the electron transfer reaction of reactive metals with reactive nonmetals such as halogen gases.
