Final answer:
To calculate electronegativity with 3 elements, you can use the electronegativity values of each element and their differences.
Step-by-step explanation:
Electronegativity is a measure of an atom's ability to attract electrons in a bond. To calculate electronegativity with 3 elements, you can use the electronegativity values of each element and their differences.
For example, let's say we have elements A, B, and C. You can calculate the electronegativity difference between A and B, and also between B and C. Then, you compare these differences to determine the relative electronegativity of the three elements.
