Question

The electronegativities of two elements are
0.7 and 3.0. The bond formed between them
would be
1) Ionic
2) Covalent
3) Co-ordinate covalent 4) Metallic​

Answer 1

Answer:

if the EN difference value is less than 1.7 then it is polar covalent bond and when it is greater than 1.7 then it is ionic bond

Answer 2

Answer:

The bond formed between two elements will be an ionic bond.

Explanation:

• Ionic bond is formed because of the electrostatic force of attraction between ions. In ionic bond the electronegativity difference of ions should be greater than 1.7.
• Covalent bond is formed by combined sharing of electrons pairs between atoms.  So the electronegativity difference should have to be very less.
• Coordinate bond is formed between an electron deficient and an electron rich elements.

For the given elements the electronegativity difference $=3.0-0.7=2.3$

Therefore the bond between these two elements will be an ionic bond. So the option (1) is correct.
