Question

An element with an electronegativity of 0.9 bonds with an element with an electronegativity of 3.1 what phrases best describes the bond between these elements?

Answer 1

Explanation:

According to the electronegativity table, whenever there a difference of more than 2.0 then the bond formed will be ionic in nature. On the other hand, if electronegativity difference is less than 0.5 then the bond formed will be non-polar covalent in nature.

As it if given that electronegativity difference of given elements will be as follows.

        Electronegativity difference = 3.1 - 0.9

                                                       = 2.2

Since, the electronegativity difference of given elements is 2.2. Hence, these elements will form an ionic bond.

Thus, we can conclude that mostly ionic in character and formed between a metal and non-metal best describes the bond between these elements.
