  • Chemistry Lab: Flame Test to Determine Unknown Substances

    Lab: Flame Test Purpose: to determine the ID of 2 unknown substances Background Information: Every atom consists of a nucleus with tiny electrons whizzing around it. The further away from the nucleus they are, the more energy the electrons have. If a metal atom is heated, the electrons get enough energy to jump higher away from the nucleus, they become “excited”. When they fall back closer to the nucleus (back to their ground state), they give off this extra energy as light. Why is the...

    Lab 20: Flame Tests Purpose/Objective: The ground state is the normal electron configuration of atoms or ions in an element. When atoms or ions in ground state are heated to a higher temperature, some electrons absorb enough energy to move them to higher energy levels. This is known as the excited state. However, the excited configuration is unstable, and the electrons must return back to their positions in the lower energy level. As they return, the energy that was previously absorbed is now emitted...
