Which of the following elements is the most electronegative? a. potassium b. astatine c. francium d. chlorine

Option (D) is the correct answer.

Explanation:

Electronegativity is defined as the ability of an element or atom to readily attract electrons towards itself.

Generally, non-metals are the species which tend to show electronegativity. Whereas metals have the ability to lose electrons in order to gain stability.

Hence, metals are electropositive in nature.

For example, potassium and francium are metals.

And, astatine is a metalloid, that is, it shows properties of both metals and non-metals. Hence, it shows both electropositive and electronegative nature.

Chlorine being a non-metal is electronegative in nature and hence, it has the ability to readily attract an electron.

Thus, we can conclude that out of the given options chlorine element is the most electronegative.

explanation:

venn diagram is pictorial representation with of circles showing the relation between two finite sets or things. the intersection part of two circles conveys the relation present in between those sets or things.

here in the venn diagram of sand and salt two circles represent sand and salt. but the area falling under the intersection of these circle represents the mixture of sand and salt.

so, in a venn diagram the mixture will be placed in a middle that is in between the intersection of two circles.
