Question

the most negative electron affinity is most likely associated with which type of atoms?
○ large nonmetal atoms
○ small nonmetal atoms
○ large metal atoms
○ small metal atoms

Explanation:

Brief Explanations

电子亲和能是指气态原子获得一个电子时所释放的能量。非金属原子倾向于获得电子形成阴离子。小的非金属原子的原子半径小,原子核对外来电子的吸引力强,获得电子时释放的能量多,电子亲和能更负。大的非金属原子半径大,对电子吸引力相对弱;金属原子倾向于失去电子,电子亲和能一般较小且为正值或绝对值较小的负值。

Answer:

small nonmetal atoms
