Which molecule has the highest electronegativity difference? (2021)
Step 1: Understand what electronegativity means. It is a measure of how strongly an atom attracts electrons in a bond.
Step 2: Identify the elements in the question. In this case, we are looking at sodium (Na) and chlorine (Cl).
Step 3: Look up the electronegativity values for sodium and chlorine. Sodium has an electronegativity of about 0.93, and chlorine has an electronegativity of about 3.16.
Step 4: Calculate the electronegativity difference by subtracting the smaller value from the larger value. So, 3.16 (Cl) - 0.93 (Na) = 2.23.
Step 5: Recognize that a larger electronegativity difference indicates a stronger ionic bond. In this case, NaCl has a high difference of 2.23.
