In this experiment, the metal cations in the solutions were initially in the ground state. When placed in the flame, the metals then (absorbed, emitted) energy as (electricity, heat, EM radiation). When this occurred, electrons made transitions from (low, high) energy levels to (low, high) energy levels. The metals were then in the (ground, excited) state. The electrons in these metals then made transitions from (low, high) energy levels to (low, high) energy levels, resulting in the (absorption, emission) of energy as (electricity, heat, EM radiation).

Cristina Odom · Answer 1

Initially, you should know that what the text describes is a test used to analyze and identify some metal ions in a compound. This is the principle behind it: first the ions are excited, by the heat of the flame, they absorb energy and the electrons are promoted to higher energy levels; after this, the electrons will fall back down to lower energy levels releasing energy as light. The flame color that is seen is related with the frequency of the light emitted.

Here is the text with the right words.

When this occurred, electrons made transitions from (low) energy levels to (high) energy levels. The metals were then in the (excited) state. The electrons in these metals then made transitions from (high) energy levels to (low) energy levels, resulting in the (emission) of energy as (EM radiation).
