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 metal or nonmetal? ? description Element 1 is a hard dark-red solid. A 10. g cube of it is tapped lightly with a small hammer. One corner of the cube breaks off into 3-4 pleces and a collection of small bits. 1 metal O nonmetal (can't decide) 2 Element 2 is a shiny silvery-gray solid. A 10. g cube of it is set on a hot O metal plate. After 1 minute, the temperature of the top of the cube has risen by nonmetal 50 C (can't decide) Element 3 is a moderately soft yellow solid. A 5 cm 5 cm square of it, metal only 1 mm thick, is heated with a flame at one end. Where the flame nonmetal touches the square the sample rapidly turns red and starts to melt, but the rest of the square remains cool to the touch. O (can't decide) 3 A robot spacecraft returned samples from the planetesimal 98765 ALEKS, located in the outer Solar System. Mass-spectroscopic analysis produced the following data on the isotopes of ruthenium in these samples: mass relative Isotope (amu) abundance 102 Ru 101.90 94.1% ARU 98.91 5.9% Use these measurements to complete the entry for ruthenlum in the Periodic Table that would be used on 98765 ALEKS, Round your entry for the atomic mass to 4 significant digits. Caution: your correct answer will have the same format but not necessarily the same numbers as the entry for ruthenium in the Periodic Table we use here on Earth el Ru 0
