The electronegativity of cesium is 0.7 and that of flourine is 4.0 The bond formed between the two is:

A

covalent

B

electrovalent

C

coordinate

D

metallic

Text Solution

Verified by Experts

The correct Answer is:
B
When the electronegativity difference between the two atoms is more than 1.9, the bond formed between the two is electrovalent.
