Explain your answer. . Materials This virtual lab requires: • A computer or tablet capable of running the simulation. Flame color test and atomic properties To sort the first few elements in the table you can observe their flame colors. 2) List three clues that indicate that a chemical change has taken place. Demonstrate how to identify an unknown element by comparing its detailed emission spectrum to a library of standard, known spectra. You dip a metal wire into a solution and put it over the hottest part of the flame. Interactive periodic table showing names, electrons, and oxidation states. Nov 6, 2023 ยท In a virtual lab, students identify mystery elements by analyzing their physical and chemical properties and comparing them to known elements in the Periodic Table. This will give off a color showing what elements are present in the compound. nduczuospuiztbuacogxrhgedhszjuxalodxzqdbjahxzi
