2. Sodium Na has an electronegativity = 0.9 and nitrogen N is 3.0. which is correct about the bond between Na and N

Polar covalent because the difference is 2.1

Ionic because the difference is 2

. nonpolar covalent because the difference is 2.1

they cannot form a bond because the difference is 2.1
3.. which is correct about ionic bond ?


Based on loss and gain of electrons

Based on sharing electrons

. Takes place between nonmetals

. Found between noble gase
4. In a polar covalent bond, the bonded atoms.(1 Point)

Share the electrons equally

Share the electrons unequally.

One atom loses and the other gains.

Both atoms gain electrons
