The electronegativity of an atom is determined by how strongly outermost electrons are pulled toward the nucleus.Somewhat like gravity,the electronegativity will be stronger in atoms with larger nuclei and closer outermost electrons.Which element has the strongest electronegativity?

Question

Quizplus · Accepted Answer

Oxygen has the strongest electronegativity of the options given. Its outermost electrons are pulled very strongly towards its large nucleus, making it difficult for other atoms to take its electrons away. This property is why oxygen is so important in biological systems, as it allows the molecule to participate in a variety of chemical reactions.
