Question

Quizplus · Accepted Answer

Electropositivity decreases from left to right within a period because as the number of protons and the effective nuclear charge increase, it becomes harder for atoms to lose electrons and become more positively charged. Electropositivity increases from top to bottom within a group because the atomic radius increases, making it easier for atoms to lose electrons and become more positively charged.
