Element 1 is a hard dark-red solid. A 5 cm x 5 cm square of it, only 1 mm thick, is flexed slightly by hand. The sheet snaps in half.
Is element 1 metal, nonmetal or can’t decide?
In the case of Element 1, since the sample broke instead of bending, we can conclude the element is brittle instead of ductile, which is typical of nonmetals.
