Test Lab was an experiment designed to show how elements react when heated. This Lab attempted to prove that when electrons are excited and then calm, they emit a color specific to the element. This test showed that there is a direct coloration between the heat energy being expelled and the movement of electrons from one energy level to the next. When the atoms of a gas are excited, in this.

In this experiment, you will be performing qualitative identification of alkali, alkaline, and transition metals. For your reference, a table 1 from your lab manual is copied below for your convenience. Before proceeding, however, read through.
Purpose The purpose of this lab was to reinforce the examination of wavelengths in photons discharged from atoms as they move from high energy to low energy, atomic emmision. Hypothesis If the element (independent variable) is placed in the fire (controlled variable), then the.
Flame Test Virtual Lab. Flame Test Chemistry - High School. Back. 1. Flame Test. How are elements identified by using a flame test? A metal salt is a compound of a metal and a nonmetal. When dissolved in water, the metal and nonmetal atoms separate into charged particles called ions. As the metal ion is heated by the flame, the electrons gain energy and move to outer orbitals. When the.
