In the table below, there are descriptions of an experiment on samples of three different chemical elements. Decide whether the element is a metal or nonmetal, if you can. If there is not enough information to decide, choose "can't decide" in the third column.
Element
Description
Metal or Nonmetal?
Element 1 is a moderately soft silvery-gray solid. A small 2 cm * 2 cm * 2 cm cube of it is put into a hydraulic press and squeezed until it is half as thick. When the sample is inspected, it has broken into many smaller pieces. Where the sample broke, the fresh surfaces are lighter in color.

Element 2 is a moderately soft silvery-gray solid. A small cube of it is put into a ceramic crucible and heated strongly. It melts at a temperature slightly above room temperature.
Metal
Nonmetal
(Can't decide)
Element 3 is a shiny silvery-gray solid. A 5 cm * 5 cm square of it, only a few millimeters thick, is flexed slightly by hand, putting a slight bend in the middle of the square.
