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 2 is a hard silvery-gray solid. A 10. g cube of it is set on a hot plate. After 1 minute, the temperature of the top of the cube has risen by 50 °C.
Element 3 is a moderately soft silvery-gray solid. Two thin rods are manufactured of the element and placed about 1 cm from each other.
When a high voltage is applied across the pair of rods, a spark can be seen jumping from one rod to another.
