Group Trends Electropositivity MDCAT Quiz: Group Trends in Electropositivity: This topic is fundamental to the understanding of metals’ behavior in the periodic table, and a must-master topic for MDCAT chemistry. Electropositivity can be defined as the tendency of an element to lose an electron and form a positive ion. This generally increases down a group, particularly in alkali and alkaline earth metals. These trends are very essential in predicting chemical reactivity, mainly in ionic bond formation and metal reactivity, which are always a part of the MDCAT exam.
