I just want to confirm if the $\ce{R-Mg}$ bond is a covalent bond which undergoes heterolytic fission during reactions while the bond between magnesium and halogen atom is ionic. Am I right or wrong?

    The R-magnesium bond in a Grignard reagent is polar covalent with carbon being the negative end of the dipole, which explains its nucleophilicity. And the magnesium-halogen bond is largely ionic. – R_Squared Sep 12 '21 at 03:06

Yes, you are correct. The carbon-magnesium bond in a Grignard reagent is polar covalent with carbon being the negative end of the dipole, which explains its nucleophilicity and the magnesium-halogen bond is largely ionic.
