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 5 cm × 5 cm square of it, only 1 mm thick, is twisted using two pairs of pliers, giving it a slight curve. O metal O nonmetal O (can't decide) 1 Element 2 is a hard silvery-gray solid. A 10. g cube of it is set on a hot plate. After 10 minutes, the temperature of the top of the cube has risen by less than1 °C. O metal O nonmetal O (can't decide) Element 3 is a shiny silvery-gray solid. Wires are fastened to each side of a 2 cm slab of it, and an ordinary household 9 V battery is hooked up so that it can feed electricity through the slab to an LED. The LED glows brightly. O metal O nonmetal O (can't decide) 3
