Question

select the correct answer. which pair of atoms has the highest electronegativity difference? elements electronegativity calcium (ca) 1.0 carbon (c) 2.55 fluorine (f) 4.0 hydrogen (h) 2.2 phosphorus (p) 2.19 sodium (na) 0.93 a. na - f b. ca - f c. h - f d. c - f e. f - f

Explanation:

Step1: Calculate Na - F difference

$4.0 - 0.93=3.07$

Step2: Calculate Ca - F difference

$4.0 - 1.0 = 3.0$

Step3: Calculate H - F difference

$4.0 - 2.2=1.8$

Step4: Calculate C - F difference

$4.0 - 2.55 = 1.45$

Step5: Calculate F - F difference

$4.0 - 4.0=0$

Answer:

A. Na - F
