D
O > F > C > Li > Be
Verified step by step guidance1
Identify the property that determines an element's tendency to accept an electron, which is known as electron affinity.
Recall that elements with higher electron affinity values have a greater tendency to accept electrons. Generally, nonmetals have higher electron affinities than metals.
Consider the position of each element in the periodic table: Fluorine (F), Oxygen (O), Carbon (C), Lithium (Li), and Beryllium (Be). Nonmetals like F and O are more likely to accept electrons compared to metals like Li and Be.
Arrange the elements based on their electron affinities. Typically, Fluorine has the highest electron affinity, followed by Oxygen, then Carbon. Lithium and Beryllium, being metals, have lower electron affinities.
Order the elements from greatest to least tendency to accept an electron: F > O > C > Li > Be.
