Question

1. choose the best answer.

ionization energy is the opposite of
potential energy
electronegativity
polarity
ionic character

1. choose the best answer.

magnesium has an electronegativity of 1.31. oxygen has an electronegativity of 3.44.
what is the electronegativity difference?
7.75
2.13
2
2.63

Explanation:

Step1: Calculate the electronegativity difference

The formula for electronegativity difference is \(|\text{Electronegativity of Oxygen}-\text{Electronegativity of Magnesium}|\).
Substitute the given values: \(|3.44 - 1.31|\).

Step2: Perform the subtraction

\(3.44-1.31 = 2.13\).

Answer:

For question 7, the answer is \(2.13\).
