Which of the following correctly represent resonance structures?

Arrange these bonds from most ionic to most covalent in character. K-F CI-F Most ionic Most covalent Answer Bank Br-F Ca-F F-F

What is the general trend in electronegativity across a period on the periodic table? Electronegativity decreases left to right across a period. Electronegativity increases from left to right across a period. What is the general trend in electronegativity down a group on the periodic table? Electronegativity decreases as you move down a group on the periodic table. Electronegativity increases as you move down a group on the periodic table. How does the trend in electronegativity relate to the general trends in ionization energy and the magnitude of electron affinity? The general trends in both ionization energy and the magnitude of electron affinity are opposite of the trend in electronegativity. The general trend in ionization energy is the same as the trend in electronegativity and the general trend in the magnitude of electron affinity is opposite of the trend in electronegativity. The general trends in both ionization energy and the magnitude of electron affinity are the same as…
