Bezerra de Castro, Caio; Teixeiro, Ivo Freitas; Marques Netto, Caterina G. C. – Journal of Chemical Education, 2020
The comprehension of the reactivity of the elements is an important goal to be achieved in undergraduate courses in inorganic chemistry. Therefore, at Universidade Federal de São Carlos (UFSCar), the B.Sc. in chemistry has a laboratory course dedicated to the chemistry of the elements. However, we have noticed a decrease in students' interest in…
