Answer (2)
Barium Nitrate ( Ba(NO3)2 ) is an Ionic bond. ;
Barium Nitrate ( Ba(NO 3 ) 2 ) is an ionic compound formed by the electrostatic attraction between the Barium ion ( Ba 2 + ) and the two Nitrate ions ( NO 3 − ). This results from Barium losing electrons to become positive, while the nitrate ions are negatively charged. The balance of these charges leads to the conclusion that the compound is ionic.
