What is the polarity of a Na-Br bond?

nonpolar covalent

definitely polar covalent

likely ionic

slightly polar covalent

slightly ionic

Respuesta :

Answer:

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 .
