Question

Two element have electronegativity of 1.2 and 3.0 bond formed between them would be

Answer 1

Difference of electronegativity between the two atoms is 1.8 so the bond would be predominantly ionic and less "covalent". For a bond to be 50% ionic and 50% covalent, the difference between electronegativities should be equal to 1.7.

Answer 2

Answer:

Two elements whose electronegativities are 1.2 and 3.0, the bond formed between them would  be IONIC BOND
