Element 2 is a moderately soft silvery-gray solid. A 5 cm x 5 cm square
of it, only 1 mm thick, is flexed slightly by hand. The sheet snaps in half.
Element 3 is a moderately soft silvery-gray solid. A small cube of it is put
into a ceramic crucible and heated strongly. It melts about not far above
room temperature.
