    likely ionic

    Explanation:

    The bond between, Sodium and Bromine, in sodium bromide salt, is ionic in nature.

    Since,

    The difference in the electronegativity of the two atom is high.

    According to Pauling scale,

    The Electronegativity of Bromine = 2.96

    The Electronegativity of sodium = 0.93

    Hence,

    The Difference in electronegativity = (2.96 - 0.93) = 2.03

    Hence,

    The electronegativity difference value is more than 1.8,

    Therefore,

    The bond is ionic in nature.
