hich of the following element has the different value of electronegativity than other three

To determine which of the elements has a different electronegativity value than the others, we first need a list of the elements in question. Electronegativity is a measure of an atom's ability to attract and hold onto electrons in a chemical bond.

Typically, electronegativity values can be found using the Pauling scale, which rates the electronegativity of elements from 0.7 (for cesium) to 4.0 (for fluorine). If you provide the list of elements, I can help analyze and identify which one differs in electronegativity.

If we assume a common list (like Na, Cl, K, and Ca), we can start analyzing:

1. Sodium (Na): Electronegativity ≈ 0.93
2. Chlorine (Cl): Electronegativity ≈ 3.16
3. Potassium (K): Electronegativity ≈ 0.82
4. Calcium (Ca): Electronegativity ≈ 1.00

In this example, Chlorine has significantly higher electronegativity compared to the others. Thus, it is the element that differs in electronegativity from the rest.

Please provide the specific elements you are inquiring about for an accurate analysis.
