Is sio2 a ionic bond
WitrynaIonic charges are not yet supported and will be ignored. Replace immutable groups in compounds to avoid ambiguity. For example, C6H5C2H5 + O2 = C6H5OH + CO2 + H2O will not be balanced, but XC2H5 + O2 = XOH + CO2 + H2O will. Compound states [like (s) (aq) or (g)] are not required. You can use parenthesis or brackets []. WitrynaQ11. A: With the increasing +ve oxidation state of central atom M, B.str. of M-O bond increases whereas thermal stability of its crystal increases.

WitrynaIonic bond: This bond is formed by the complete transfer of valence electron(s) between atoms. It is a type of chemical bond that generates two oppositely charged ions. In ionic bonds, the metal loses electrons to become a positively charged cation, whereas the nonmetal accepts those electrons to become a negatively charged anion.
