Quizplus · Accepted Answer

Metallic character decreases across a period from left to right. Carbon has the least metallic character among these elements due to its small atomic size and high electronegativity. Nitrogen has one additional electron and one additional energy level compared to carbon, allowing it to attract electrons more easily and form stronger covalent bonds. Oxygen has an even higher electronegativity due to its smaller size and increased nuclear charge, making it even less metallic. Fluorine, with the highest electronegativity and smallest size, has the least metallic character. Therefore, the decreasing order of metallic character is C > N > O > F.
