Question

the electronegativity of caesium is 0.7 and that of fluorine is 4.0 the bond formed between the two is​

Answer 1

Answer:

Ionic . CsF is an ionic compound .

Caesium is the least electronegative element and fluorine is the most electronegative one . So , they form a bond by formation of Cs+ and F- ion

Answer 2

The bond formed between the two is​ ionic.

Explanation:

A polar covalent bond is defined as the bond which is formed when there is a low difference of electronegativities between the atoms. Example: $HF$

Non-polar covalent bond is defined as the bond which is formed when there is no difference of electronegativities between the atoms.Example: $H_2$

Ionic bond is formed when there is complete transfer of electron from a highly electropositive metal to a highly electronegative non metal. The electronegative difference between the elements is high.Example: $CsF$
